I am writing you to find out if you can help me figure out what is wrong with me. I am 23 years old and for about the last 2 years I have been having a serious sexual problem that i just cant seem to figure out. My boyfriend of 5 years and 7 months thinks i am cheating on him because I don't want to have sex. But when we do have sex it is not because I want to i do it for him but my problem is this when we do have sex it deos absolutely nothing for me and afterwords I feel sick to my stomach and I feel dirty and like i did somthing wrong. If there is a cure for what I am going through could you please let me know I would greatly appreciate it.
