My boyfriend and I are both virgins but his sex drive is extremely high?

So basically the situation is that me and my guy best friend have decided to date again. But this time is a little different: I recently made my own purity vow and got a purity ring. He says he's okay with it and respects my decision yet when he said it he wasn't enthusiastic about it. This lead to a rather awkward incident on late Friday night and earlier Saturday morning when after a heated make out session we dared each other to see who could make the other one lose control first. He tried to make me uncomfortable by putting his hand up my dress and wander outside my panties. Needless to say, I knew what he was doing and it didn't work. Then he hesitated for a moment, because he was going to try to finger me then remembered I was wearing a purity ring and drew back. Then, he tried to make me uncomfortable by daring me to touch his penis, first by touching him through his pants. I did because he knows I love dares. Then he dared me to go inside his pants and touch the actual penis. I did. Then I felt dirty, guilty, and disgusted with myself. I could've said no but for some reason I didn't. I feel like I'm competing with his past relationships: he's done a lot more sexual things than me---oral,etc. He's just hasn't done full blown sex. Before Saturday, I've never touched a penis before and have never gone beyond kissing. I feel like him and I are on two different levels of sexuality, besides an age difference (he's 24 and I'm 20). We like each other a lot, but I feel like there should be some options? I can't have sex with him (oral, anal, etc.) and I can't jack him off (because that technically is a form of sex right?), so that means I'll have to give the option of an open relationship to him. If I can't have sex with him somebody else will. Is this a good idea?
