<human>: Give me the gist of the text in a nutshell

I'm posting a thread here because I don't know if I'm being a dick or not.

My girlfriend and I don't live together we still live with our parents, and I have some family staying over my house so there is always someone at my house, meaning no privacy. The only times we can have sex is in the morning at her house. But it's from 8-5 when her sister is at work. So pretty if chunk of time. 

But she sleeps in until 11 or whatever and I really want to have sex with her but she doesn't seem to care. Today were hanging out with a group of people in 3 hours and she only wants to get picked up, even though she's been home alone for a lot of hours. But I want to have sex, and i know she likes sex. But she just likes to have it when im in front of her and if the situation just happens to be right. I respect her space but this happens often and im in a relationship and a benefit from a relationship is access to regular sex. But I can't just invite myself to her house. I can't just be like umm can I get there earlier? It will seem unattractive and desperate and my motives obvious.
<bot>: girlfriend and I can't have sex whenever. We have time to have sex at her house in the mornings and although i respect her alone time I feel like she makes no effort to put in some intimate time.
