The first time I've come across this idea that a woman's body is the root of all evil is the manosphere.

Meanwhile a lot of my friends prefer a woman who has a sexual experience. It makes everything easier.

How can you expect a 30 old woman not to have sexual experience. The fact that she's seeked out sex in the past is a sign of a healthy human being with healthy needs.

The only way for you to obsess about this is

A) You're a religious nut. (In that case, more power to you)

B) You don't have experience yourself or you have naturally gross sensory motor skills, leading to you feeling unsure about your skills. Either way, it's not open heart surgery. You'll figure it out

Unless the woman has slept with a huge number with guys which is a sign of low self-esteem and and impulsive personality (in guys, too), then who cares if she's had some hookups. Most people are still serial monogamists and if you don't want to do anything with very promiscious women, then simply don't bother with that demographic.
