You are in your mid 20's. Don't lose your virginity to a provider. I am not sure how you look but you don't have to be a stud to get laid. Don't start off paying for sex.....I'm assuming that you have never had a long term relationship if you are a virgin. Going this route will certainly not help you to do so at your age.
Just work for it, and you should sleep with a woman for the 1st time who wants to be with you, and not because you can pay her donation to act like she wants to be with you. I just think this route is a bad way to go for you. You're a young dude, your time will arrive.
You've made it this long and you are still alive, and lack of pussy won't kill you, so keep living your life and lose your virginity to someone who is not checking your work references to find out whether or not you are a cop and who is not billing you by the hour for services rendered by taking your virginity.
The choice is yours, I hope you take my advice but if not, I understand. I just think that your first time should be with someone who actually is with you for you, and not because you stopped by the ATM before you visited her incall.
There are many jaded guys on this site that may make you think that P4P is the only way to go. That's not the case. Just as the providers are on here, there are a lot of great "civilian" ladies out there.
