I'm 16 and I have had sex with a few people. I have been lucky enough to have had sex with guys who are above average. I know I'm still tight because guys tell me that on the spot, but whenever I have sex with a guy who's dick is kinda thin I can't feel anything and I tighten up the muscles and like squeeze, the guy notices it but it still doesn't make a difference for me. The guy isn't nessasarily small in length.. does this mean I'm lose or what?
