temple

i have had this pain in my lower right side that started about 6 months ago, and comes and goes, but was the worst for the first week. it kind of feels like a strained muscle... but i also have pain during sex that only started at about the same time. ( it hurts when deep and at certain angles) i am too frightened to go to the obgyn because ive never been and im scared theyd say i have something bad. has anyone had these symptoms or know what they are connected to ? sometimes, i wonder if it is mental, because im not really in love anymore, or very attracted to my bf. please help. thanks, t
