I realized among my friends , not only do people not care about it, but they prefer women who already have sexual experience. It makes sense as it makes things easier.

Why would you expect a 29 year old woman not to have sexual experience ? The fact that she's seeked it is a sign of healthy person with a normal sex drive. It would be stranger if she didn't.

The only reason to care about this is if

  1. You're religious.
  2. Insecurity

If you're overly religious in the west (especially europe), you're not going to be compatible with most women anyway. If you're insecure, I don't know what to tell you.

The only time body count matters if that person (man or woman) has a huge body count which most people don't. Then it becomes a question of "why?" Because sleeping around like a rockstar isn't about enjoying sex, it's about compulsively seeking validation through sex which is an indicator of low self-esteem which is unattractive. The solution is easy, don't go for these women/men. The majority of people are still serial monogamists.

TLDR : Nobody cares. Nobody cares if you care
