I've become involved with a guy that has me so obsessed with the way he satisfies me sexually its driving me crazy. His name is Eric, he's 45 years old and other than the sex I don't even like him. I am only with him once or twice a week since last May and continually tell myself to stop seeing him. It took several months and has gotten to where it seems he is controlling me by permitting him to dominate the types and ways we have sex. Its clear to me now that his desire to humiliate me is a big part of our relationship. He openly admits how much he likes watching me orgasm and each time I am with him he counts how many I have. I can't think of one sex act or position that I have not experienced. There are some nights that I orgasm 5, 6, or more times just by the relentless ways he stimulates me. Intercourse is only like for-play with Eric including the anal and oral sex we have. He enjoys spanking me, shaving me inspecting my body in embarrassing situations especially when using his collection of sex toys. A few months ago I found out he has been filming me and refuses to let me see them. I've gotten into arguments with him a few time and know for sure now on several occasions there was at least one or more other guys in the room, when he had me tied down and blindfolded. He hasn't admitted blackmailing me but when I threaten to stop seeing him he mentions how "terrible" it would be if my co-workers or my parents saw his videos and photos. I dread now when he insists on tying me down with a blindfold. Eric only talks to me but for many months I know there is someone else there watching. This is when he uses an assortment of sex toys penetrating me anally and vaginally. The most humiliating thing is how I can't help myself staying aroused and having continuous orgasms knowing at least one other guy is watching me. When I ask Eric if there are other guys he only says maybe and then denies it while laughing. When he blindfolds me I can't see a thing and fear he is letting other guys use the sex toys. I never wondered months ago because as I am tied down Eric sometimes pulls my butt down to the end of the table and either has vaginal or anal intercourse with me. The last few months when its been done I suspect Eric is letting another guy screw me and its always with a condom. The worst thing is as much as Eric controls me I have never been more sexually satisfied with the ability to stay aroused for so long. I have had sex with quite a few guys but never orgasmed as many times as I do with Eric. He denies letting other guys do anything with me but by now I am sure he is lying and I'm afraid they might know me. Nothing is ever said but it just feels different than the way Eric usually penetrates me and the way he trusts himself into me. I can't say for sure but he won't admit to anything. I'm a fool letting him do this and swear to myself I'll stop seeing him but every time he calls I go to him. Another reason I should stop is the fact he has another woman who he told me is just a friend. I wouldn't be surprised if there were other girls he did this with. He is a jerk but manipulated me to the point where I just put up with it for my own sexual needs. I've been dating another guy for a few weeks but have only had sex with him 4 times so far. I enjoy it but am never fully satisfied. Eric has ruined me with his ability to seemingly be able to keep me aroused for hours at a time and have me orgasm to the point of exhaustion.
