<human>: So, this might be a bit of an odd question, but I'll give it a shot.  BF and I have been dating for 3 years, and we're both about to graduate from the same college.  We haven't had PIV sex yet because we don't want to risk getting pregnant.  However, I really enjoy making out/touching each other.  He, on the other hand, only enjoys this very very rarely.  Most of the time he participates grudgingly until I just push him away.

I'd be able to get used to his lack of interest in these things if it wasn't for the fact that he likes to tease me.  He likes to squeeze my butt and boobs, he'll stare at them and make favorable comments, he'll tickle me, etc.  After a while of this I start to get excited, but it doesn't take a genius to see that he doesn't want to go any further, ever.  

I have tried talking to him about this, including just last night.  But we both always get wrapped up in our emotions--he gets sullen and apologetic but won't offer explanations, and I start crying about not being attractive or desired (which he denies).  

The only explanations I've got are "making out gets boring" and "I like it when we build up to it", but I don't understand how to cater to him in this way.

Honestly, I would much much prefer him saying "I don't really like this stuff" and not touching me intimately ever, than him teasing me and grudgingly engaging.

What can I do, reddit?  Please no 'dump him' comments, I plan to marry this guy in the near future (once we graduate and get our feet on the ground).  He's wonderful, smart, kind, and perfect in every other way.

Can you condense the text into three sentences or less?
<bot>: Boyfriend gropes me and teases me but won't engage in anything further.  Claims he's attracted to me but it's hard to believe at times
