Is there something wrong w me!?!

*PLEASE NO NEGATIVE COMMENTS*

Me and my boyfriend have been together years and even have a baby together. But often times he has trouble getting hard and he doesn’t like to have sex but maybe once every couple of months. I just feel like there is something wrong with me. When I ask him about it he just says he doesn’t like to or he’s just got stuff on his mind and that I’m perfect. But it still makes me insecure like something is wrong with me. I don’t think he has ever done this to any other girls in his past..:(
