Female sex offenders are underreported, and many victims never tell anyone about the crime, giving this false impression that most sex offenders are men. There are various types of sex crimes including forcible rape (using force, often physical force or incapacitation to get someone to have sexual intercourse with someone against their will), statutory rape (non-forcible voluntary sexual intercourse with an underage teenager), child molestation (any sexual contact involving a child below puberty age), voyeurism, exhibitionism, etc. Sexual coercion is another form of sexual assault, which involves forcing someone to have sex with you when they don't want to by false promises, verbal threats, constant nagging or pressure until they finally say sex, etc., which is different from rape.

Anyways, here's information about female sex offenders. We're going to examine each type:

Female child molesters:

Female child molesters typically are in their late 20s/early 30s, and sometimes might have a history of mental illness and many were molested or physically abused in their childhood, often coming from dysfunctional homes. Many of them might co-molest with a male child molester, who is sometimes a husband or boyfriend. Some might do it because he's abusive and she's forced to but sometimes they aren't forced to and only do it because they want to or because they're dependent on him. Nonetheless, there's also some female child molesters who act alone. Lone female child molesters are not at all unusual. Female child molesters have younger victims than male child molesters, and while male child molesters have more girl than boy victims, female child molesters have just as many boy victims as girl victims. For example, 40% of men who were molested in their childhood said it was a female perpetrator compared to 4 to 6% of women molested in their childhood (these percentages could be much higher because many people molested by a woman in their childhood might lie and say a man did it). Female child molesters also are far more likely to be parents or caregivers of the victim than male child molesters. As a result, many people molested by a woman in their childhood might not recognize it as abuse because they believe what happened was normative nurturing behavior. Female child molesters often have victims younger than male child molesters and their victims are usually under 12 years old. In fact, female teachers who molest their male students typically have male victims under age 12, contrary to the 20-something year old female teacher and teenage male victim stereotype that the media emphasizes. 30% of student-teacher sex crimes involve a female teacher, and this percentage could be much higher due to underreporting. Although female child molesters are more likely to be a mother or caregiver of the victim, some can be a sister, babysitter, teacher, family friend, neighbor, acquaintance, etc.

Female statutory rapists:

The difference between a statutory rapist and a child molester is that child molesting is defined usually as children under 14. Statutory rape generally refers to underage teens ages 14-17. This next type of female sex offender is a woman who commits statutory rape with underage teenage guys, not to be confused with women who forcibly rape men, given that forcible rape is different from statutory rape.

Male statutory rapists typically have victims ages 14 and 15 (although this could be because the age of consent is 16/17 in many states). Male statutory rapists are typically not that much older, about around 20 years old which is about 5 or 6 years older than a 14 year old (nonetheless this is still statutory rape). Female statutory rapists, on the other hand, tend to be older than that compared to their male victims. Female statutory rapists tend to be several years older than the underage guy, typically in the mid-late 20s (however this doesn't mean they cannot be in their early 20s). Women who commit statutory rape with their male students typically did not experience child molestation in their childhood but did experience verbal and emotional abuse.

Female statutory rapists often had early sexual experiences with older sex partners themselves. For example, the mean age of their first sexual encounter was at age 13 and the mean age of the older partner was 23.5. They also display elevated levels of schizophrenia and hypomania on the MMPI, which is associated with unconventional lifestyles and socially inappropriate behavior. Some researchers found in clinical experiences that women who had committed statutory rape with teenage guys often displayed some defensiveness and a denial or minimization of their actions as well as the possible impact of their behavior. The women were unable to acknowledge any character flaws in themselves, and tended to have a history of dependent relationships and substance abuse. Overall, the description and analysis of the adults in statutory relationships are based on tiny and potentially unrepresentative clinical samples, and have limited generalizability, but do give some evidence about a diversity of types.

Women who rape men (forcible rape) and women who commit sexual coercion:

This type of female sex offender is the least likely to be reported. They are the least likely to get caught, but women in self-report surveys have admitted to perpetrating sexual assault or sexual coercion.

First, the difference between rape and sexual coercion should be addressed. Sexual coercion typically is against one's will and sexual intercourse occurs through verbal threats, false promises, constant nagging and pressure until one says "yes", threats to expose secrets about them or end the relationship, etc. Rape is typically force used to get someone to have sexual intercourse with you by using physical force or incapacitation. Women do what's called "made to penetrate" or "forced to penetrate", which is still rape.

According to a lot of information I read, sexually coercive women and women who commit rape sometimes might have possible hostility towards men, and most were sexually victimized in their lifetime or had a history of prior sexual abuse (although there are some here and there who never experienced this). They often have manipulative ideas of what relationships should be like and they tend to be more feminine than most women. They tend to be hyperfeminine. Hyperfemininity is a strict adherence to stereotypic feminine gender roles, and often hyperfeminine women tend to believe their success is based on whether they have a relationship and whether they're sexually active. They believe marriage is more important than career and are attracted to macho men. They expect men to be sexually and physically aggressive in relationships and sexually/physically aggressive men attractive and they tend to be attracted to bullies, too. They are hypersensitive to men rejecting their sexual advances and this often leads to them being sexually aggressive towards men. They often are sexually violent towards men in order to achieve intimacy, affiliation or interpersonal belonging, which is perhaps why they value relationships so much. These are characteristics of hyperfeminine women, and hyperfeminine women are more likely to commit sexual assault against men. Hyperfeminine women and sexually violent women also tend to be highly narcissistic than most women and they have more sexual experiences and/or early sexual experience. They can have more consensual sexual partners on average. It is also possible that they are more physically abusive or even verbally abusive towards their boyfriends/husbands.

I didn't save all the sources I read but this is what I read.
