<human>: Hello Reddit, throwaway account. 

I am stressing myself out lately over my relationship. We have been together for 2 and half years, we live apart and only see each other once or twice a fortnight, on weekends. I love my GF very much and she is kind, caring and beautiful. However, I have a high sex drive, I think about it a lot, I like to talk about sex and like the idea of sending each other nudes when we are apart, that sort of thing. My SO has little to no interest in it at all. As time has gone by I have mentioned the idea of sending pictures and she doesn't ever want to, which bothers me. But I respect her decision and don't want to be forceful. I don't talk bring it up anymore or ask for pictures or sexy talk because she never takes it very well and tends to get upset. Over the last few months I have been getting more and more agitated because I seem to want it more and more.

Now when we are together we have sex, we enjoy it and its awesome. It isn't boring sex but its certainly not adventurous. But lately she has been losing her sex drive and its always me who instigates things when we are together, and even though she is saying she enjoys sex its becoming quite an effort to make things happen. 

When we are apart during the week and I am horny and want to exchange pictures, or sext I don't feel comfortable talking to my GF. This has led me to think about other ways of satisfying myself, (tinder, kik, snapchat - I haven't done this because I see it as unfaithful) and think about whether I am making a mistake in being in a relationship when I want to be enjoying, and exploring sexual activity. 

Am I being an arse? I don't know what to do. I think its a pretty stupid reason to end a long lasting relationship just because I am hornier and want more sex. And I know if I did end it and went and shagged some randoms I would instantly regret it. The problem is talking about it to my GF just ends in disaster.

Give me the gist of the text in a nutshell
