Question

My boyfriend complains about sex. Majority of the time I am in the mood and sometimes I would randomly touch his penis or try to give him head. He complains about and said it can be annoying. I don't understand him because guys before him never turned down sex from me ever and he does which is weird because he was a virgin when we met and I assumed he would be all over me all the time. I never turn him down at all and it bothers me sometimes. Has anyone ever experienced this before?
