This isn't how "boyfriend and girlfriend" works. He's manipulating you. This entire situation is not right. Just because he said he's seen your vagina does not make it any more okay, if anything it makes it worse. You don't want to lose your virginity but it seems like this guy is expecting more despite him telling you he doesn't. People can lie. Just because a guy tells you that he won't expect you to have sex with him doesn't mean he believes that. I understand that you're fascinated with erections and penises, but it'd be a lot safer to keep that curiosity at pictures or something for now. Like already said, you'll have plenty of opportunities to see them.

In your post you even SAID it turned out he wanted more followed directly by you saying he said you didn't have to have sex. This is not a good situation to be in.
