Ive only recently lost mine (im 23), and part of me regrets it.
I didn't have any issues/wanting to keep my virginity type thing.
But think i made a wrong choice in the guy.(he was great to start with, but now im doubting him) I think it was a combination of him talking me into it, him being the first guy that showed any attention to me that way, him saying the right things, and the heat of the moment. I was in over my head.
For those who are still virgins, be in love. And make sure the guy is trustworthy and isn't just wanting sex - not by just telling you he doesnt, make him prove it somehow. right now, im starting to believe all men lie. thanks to just one man.
