question: My boyfriend has had problems keeping an erection during sex. We ve been together for 8 months now and only sometimes he can last the entire time. He says it is something in his head and he could be right, but last night he told me when it goes limp, it feels numb like he just can t feel anything. He is only 30 and said this has only happened before with 2 other girls in his life. The others he has been with, haven t experienced this problem. Please help. I love him very much and want to help him.
