My boyfriend prefers that we not sleep over after sex. . .yet. Strange?

Things are still going very well with my guy generally. We have been dating for about 3 months and see each other 3x a week and have very good communication. I was out of the country for the holidays for about 10 days but we were in touch with msgs every day and talked on the phone every other day. We celebrated New Year's Eve together (dinner and then went to a small party at my friend's place) and then most of New Year's Day too including hanging out with some of his friends.

Sex is still pretty good and he is very good about looking out for my needs there;) He also really just loves my body which is great. One little quirk and I guess it relates to that last post I had where he said he would go home rather than stay over (from a few weeks ago). After New Year's Eve he came over and we traded our xmas gifts. Then we had sex and I guess he had that thought again so he went hom quite late after. But we did then meet for brunch and spent the whole day together through 11pm on New Year's Day. He did bring it up because he realizes I might think it is odd. He said he thinks it is better to be slower than faster with the sleepovers. He said it's a matter of habits and he didn't want to start that yet. He said that's what he had to say on it but if I wanted to talk about it more, I should bring it up. Otherwise we are going for a long weekend in two weeks and he is very attentive, pays for everything still even if I offer. I'm just curious what you think about that?

We have each stayed over at the others' place one time each. He communicates a lot and brought it up the next day at brunch (yesterday) and said if I want to talk about it more, I should let him know. I haven't taken him up on that. . .yet.

Perhaps I should follow-up with him and tell him that we should slow down on sex too because it goes hand in hand for me? I mean if he wants to be careful on forming sleepover habits, I don't want him to form a habit of regular sex. . .and all. . .right?
