<human>: Could you distill the essence of the text into 1-3 sentences?

Hi reddit,  I'm having some worrying thoughts that have been playing on my mind for a few weeks now. Me and my wonderful SO have been 'dating' for over a year and an official couple for six months, although we were close friends for five years prior to any romantical relationship started. 

Due to work and college I find myself waking up from anywhere inbetween 5:00 in the morning to 6:30 and this means I fall asleep around 10:00 pm. 

The problem with this is that I still live at home with my brother, sister, mother and father. This means any sexy times with my SO have to wait until they're all asleep and it's certain no one will interrupt us. Since I returned to college after the Christmas break I really haven't been able to stay awake late at all, which means nothing happens and this is really unfamiliar for the both of us. 

I don't like falling asleep and would much rather stay up with him but I just can't help it. I rest my eyes and next minute I'm asleep. I think this has been bothering my boyfriend, he does ask me to try and stay awake so do I know it annoys him to some extent. We talk all the time over messenger and I've been receiving a lot more half-assed replied like 'yeaaap' which makes me feel he doesnt want to talk to me. He also comes to mine every Wednesday night so we can leave for college the same time the next day. He's been coming for months to do this and this week he decided not to as he's going out tomorrow night? I feel like it has something to do with the lack of sex but I don't know how to bring it up to him without seeming paranoid or nitpicky. 

Sorry for the novel. I really do love him and it would break my heart if I knew this was the reason behind his what I think is quite distant behaviour.
<bot>: Fall asleep on SO before we can do the sex, feel like he doesn't want to see/speak to me as much.
