Why is he concerned I am "too innocent"?

the way you respond top that is you keep going out and have fun.

He's a player. Looking for sex and not commitment.

He's having doubts about sleeping with you because he thinks you're too good of a girl. You're too nice, too pleasant, very feminine. And he knows that he will hurt you should he stick his d*ck inside you. Because he won't stay around for long. It's obvious. And interesting to you.

"Then he wanted to know about what I've done sexually... and said he was glad I wasn't a virgin"
--> and lemme guess - that was a lie. Lied to him about your V-card because you like him somewhat and want him to think you're experienced, right?
Meh ... people bullsh*t to get approval from others. Whatever.

How to respond to that? Who said you need to?

Maybe he reckons his perversions are too much for a virgin like you to handle lol?

I think I get what he's feeling. He say's your too nice, it basically mean's he feels like you could go out with someone better than him and he may feel he's not good enough for you or not worthy for you and may also feel that he would screw you over somehow and change you without trying. It's like he value's you so much that he doesn't want to do anything that would change or harm you because he feels he would ruin you somehow if he did. This is only if he is actually interested in you. Do you get what I mean at all?

Well, I wouldn't want a $hithead like me corrupting some innocent lass. I wouldn't want a girl to waste her innocence on someone like me.

If he's not just kidding around, it's strange.

Look, don't listen ti the other guys. They don't know anything. Talk to your love interest about it and make him understand that you're confused with what he said. Don't be passive. Be direct. You won't hurt anyone's feelings. Nothing bad will happen.

Hes not interested

I think he tried to say he wasn't interested, with the "don't want to corrupt you" bullsh*t. Translation let him corrupt someone else.

Simply put, he's concerned that he'll be dating a girl that isn't going to have sex with him.

Remember that all non-asexual guys, want sex from their girlfriend. Even if he IS waiting till marriage (which this guy isn't), the urge to WANT to have sex with you is still there, although suppressed.
