<human>: So my and my girlfriend live at different uni's. 40 minutes away which is probably the best deal your going to get from separate universities. We would see each other at least every week and a half, sometimes two/ three times a week depending on what days we had free.

We had a small hiatus last year, I broke up with her as the distance (which was closer to two hours) got too much for me. After 4 months we reconnected and had an excellent summer.

She now tells me she finds me sexually unattractive and refuses anything sexual. ( I saw her the weekend before and was not the case) I believe it is down to stress and pressure and that things will sort themselves out. She disagrees.

I ask the obvious questions, did I do something? is there someone else? etc
Nothing apart from the fact she isn't horny.

We eventually decided to take a weeks break from each other and then talk about it next weekend.

Apologies for the long intro Reddit, What can I do to bring back the spark? She wont let me try anything sexual at all. 
Anyone with experience with this sort of thing got any tips?

Can you condense the text into a few key points?
<bot>: my girlfriend doesn't find me sexually attractive, wont let me try anything sexual to turn her on. Need tips by the weekend.
