When my boyfriend and I first got together, we would have sex on a regular basis, but now he always says he's "to tired" or comes up with excuses every time I wanna have sex with him ... I know it's not because of me, or at least it shouldn't be he says it isn't. But I can never get him to have sex with me or anything ... & it hurts and makes me feel like he doesn't want me anymore or something ...
