Throwaway, on mobile, TL:DR at bottom, etc. 

My boyfriend (20M) and I (19F) have been dating for about a year and a half. This is my first relationship, and his second  We are very happy together, and we try to spend as much time together as possible. 

A few weeks back, the topic of becoming sexually active came up. We tried it a few times, but I was just never interested. I don't have any religious/moral objections to it, I just don't get anything out of it and it makes me slightly uncomfortable. 

He, on the other hand, has a very high sex drive. He always wants it, especially after we had sex for the first time. It's to the point where he says that it affects his everyday life, like his sleep, concentration, etc. 

The other day, he was talking about this situation a lot. He was sending me articles about the benefits of sex, saying how he wishes he could have sex with me so that he could sleep better, stuff like that. It felt to me very manipulative, and I asked him to stop trying to talk me into sex because it made me uncomfortable. He almost immediately apologized and backed off. He said he didn't intend for it to sound that way, but if it did then he would stop talking about it. Our conversation has been sparse since then.

We both have the day off today, and normally I would go straight to his house, but upon asking him if I was okay to head over (he sleeps in so I wait until he's awake) he said maybe I shouldn't today. 

I feel bad because it's affecting his life so much, and I want to help him with it, but it seems the only solution is me having sex with him regularly, and I don't want to do that. So am I the asshole for not having sex with him? What should I do? 

TL:DR I don't really care for sex and it makes me slightly uncomfortable, but my boyfriend has a super high sex drive and the lack of action is affecting his daily life. Am I the asshole for not having sex with him?
