How can guys tell if your really a virgin?

My long time friend which is now my boyfriend is like a real "player" but not so much really I don't know what to call him really so I know he's really experience in ...we were talking and the virgin question came about and I always thought he knew that I wasn't, I think he know and isn't too sure or just want me to tell him again. I consider myself a virgin still mentally you can say but physically I'm not...the reason I think I'm still a virgin is because I never really went in on it like as soon as I felt pain it was time to stop and I never seen or notice any breakage of my hymen..my last time was the summer of '08 (Long time) I know so my question is would my boyfriend think I'm a virgin even though I'm not and I tell him that I'm not? but he feel how "tight" I am would make him believe that I am a virgin. I'm not trying to confuse him or anything I want to know for my own knowledge can guys really tell?!?!?!!?
