am worried about my mom and my step dad they been together for 13 years and he never really like having sex and my mom gets mad because she says that he has sex with her 4 times a month and she wants to leave him is it normal for a guy not to be sexually active? no my step dad is not gay he told me one time that he feels bad but hes just not as sexually active as my mom and he doesnt know how to pleasure her when their having sex.
