sex hurting for anyone else?

Does sex hurt for anyone else..? I seriously cannot get wet. I feel really bad cause I know my boyfriend will have to go w/o sex for weeks after I give birth so I've been trying to have sex with him. (I'm 38 weeks) but it seriously just hurts. My sex drive is super low lately, well he has an extremely high one! Even if I'm Pregnant or not. So does anyone else have this problem..? Is it normal towards the end of pregnancy? We were having sex almost everyday until about my 34th-35th week.
