My boyfriend and I will be going on one year together and our sex is fun its great and its once every 1-3 days (it varies) he constantly tells me how attracted he is to me and how sexy I am and how he would never want another girl n has never had the connection or sexual chemistry with anyone even close to what we have. I'm 21 and he's 23. But when I randomly or spontaneously want to go to play he is more and more saying he's tired or has a stomach ache. Well for 2 months this is his exscuse.. Like really? You have a stomach ache or are tired at the exact timing in when I'm in the mood? I'm scared he isn't being honest about why he doesn't want it like I do or as much because he doesn't want to offend me so what do I do? Sometimes he doesn't even acknowledge me insinuating I want to have sex and I think its because again he doesn't want me to get upset. Again were having no issues in bed so why the random change? Idk what to do as a girlfriend or if I should back off because talking about it only annoys him... Help/advice?

He is tired ? After a year he is getting used to the relationship and not willing to work hard on sex when he is really tired? Often at one to three years couple see frequent sex slow down.

But if you can't sit and talk ( not in bed) about this and be honest, there is a lot more problems.
