Of course women have purely sexual urges and there are many women who want hookups/FWB. It is very common. It has nothing to do with age. I could list at least five female friends who are currently looking/finding people to hook up with, and they tend to choose people over 25. The only person who is obsessed with age is YOU. The "problems" you keep identifying are not real; they are things you imagine. If you feel your only options are escorts, then there is a problem with your thinking that you should probably address in therapy. If you think women want men in their late teens/early twenties, then how come women were not all over you when you were that age? Doesn't that prove your thinking is flawed? Your problem is that you are creating mental obstacles for yourself-- you are afraid or lack confidence or something. The problem is not age. The sooner you address what is actually going on for you, the sooner you can start finding the companionship you seek.
