Orgasms ca come and go hon, maybe you're just not stimulated enough. I wouldn't worry OR start placing blame, try talking to him (not in a negative way, more like "I love it when you do this" etc)

I try telling him what i like but he just wants to go hard and fast. Forplay is him asking me if i want to do it. Do you think it is because he is younger then me or doesnt age matter
