<human>: Can you give me the gist of the text in a nutshell?

My long term boyfriend and I have hit a wall. We've been bickering like crazy and can barely get through a week without a misunderstanding. Up till now he's mostly left it up to me being stressed out about college and the many other things going on with my life, but now I'm coming to pinpoint it to the lack of intimacy.

Everyone else seems to be much more sexually active than us two. We live separately with our families, and rarely ever have the houses to ourselves, but my boyfriend keeps insisting that this is the only time and circumstance when we can get intimate. I've proposed renting a hotel room on several occasions but he keeps saying he's uncomfortable but is willing to try it out sometime (keyword being sometime, because up until now, that time has been never). It's not normal for 20yr olds to only have sex once a month/two months and I'm starting to get worried. Is it me? Is it something else? Does he not want sex? What's the problem?

I need the affection, I know he does too, but instead of doing something to resolve this issue he just keeps ignoring it!
<bot>: 20yr olds that bang once every two months, how do I approach this without a full blown fight and cheating allegations?
