The photo image of men who haven't had sex since age 18 seems to be a made up image. I never found it online. BUT, I did find that in like 2018, about 28% of men haven't had sex in a year, compared to only 18% of women.

Here's some more data:

COLLEGE WOMEN ARE NOW MORE SEXUALLY ACTIVE THAN COLLEGE MEN

In a sample of 784 college students in a survey conducted in 2015 by The Cut, they asked respondents about their sex life. 40% of college students reported being virgins. When asked if they are sexually active, 49% of freshmen and sophomores said yes and 51% said no. 57% of juniors and seniors said yes and 43% said no. When asked if they are sexually active, 59% of women said yes and 41% of women said no. 51% of men said yes and 49% of men said no. This means that college women are more sexually active nowadays than college men, with 59% of college women being sexually active compared to only 51% of men. 52% of virgins said they have never been in a relationship, compared to only 4% of non-virgins. 17% of college women reported using dating apps compared to 27% of men. Only 14% reported finding sex partners online. In another survey, at least 80% of college women said they've either had sex before or have at least hooked up or had their first kiss or done oral sex or mutual masturbation etc. etc.

YOUNG MEN ARE NOW MORE LIKELY TO BE SINGLE THAN YOUNG WOMEN

In the 80s/90s/2000s, men and women didn't differ much in prevalence of being single. This all changed in the 2010s. In 2012, 43% of men said they have no steady partner, compared to only 27% of women. Mysteriously, in 2014, it was 33% of men compared to 32% of women. In 2016, it was 43% of men and 27% of women, and in 2018, it was 42% and 31% of women. Being single skyrocketed for men but stayed the same for women when it comes to prevalence.

In Pew Research survey in October 2019, 51% of men age 18 to 29 said they are single, compared to only 32% of women age 18 to 29. 27% of men age 30-49 were single compared to just 19% of women age 30-49. Interestingly, 49% of 65+ year old women are single compared to only 21% of men age 65+. This could be because men on average die earlier and men might marry a little later than women.

I read that 75% of singles age 65+ aren't looking for a date, and that 71% of single women over 40 aren't looking for a date. I read that 67% of men age 18 to 39 are looking for a date and only 33% aren't, whereas 61% of women age 18-39 are looking for a date and 39% aren't. 63% of singles age 18-29 are looking for dates and 37% aren't, whereas 61% of singles age 30-49 are looking for dates whereas 39% aren't.

About a third of never-married single adults (35%) say that they have never been in a committed romantic relationship. These singles are younger on average – single adults who have never been in a relationship have a median age of 24, compared with 35 among those who have been in a relationship. Still, 21% of never-married singles age 40 and older say they have never been in a relationship. Roughly four-in-ten (42%) of those younger than 40 say the same. Never-married single men and women are about equally likely to have never been in a relationship (35% and 37%, respectively). Those who have never been in a relationship are less likely to be looking for a relationship or dates than never-married singles who have some experience with committed relationships (53% vs. 67%).

Women who have found it difficult to date are much more likely than men to say a major reason for their difficulty is that it’s hard to find someone who meets their expectations (56% vs. 35%) and that it’s hard to find someone looking for the same kind of relationship as them (65% vs. 45%). For their part, men are more likely to say difficulty in approaching people (52% of men vs. 35% of women) and being too busy (38% vs. 29%) are major reasons it has been difficult to find people to date. 53% of singles ages 18-29 say they feel pressure from society to be in a relationship and 47% say they experienced pressure from family to start a relationship. 42% of singles age 30-49 say they feel pressure from society to be in a relationship.
