Kinky sex

could somebody tell me what they think about a man wanted to watch porn and to act some, like slapping, suggesting a threesome, and not being able to have a loving sexual relationship, but avoiding being touched above the neck and getting his hands on top of his head so the woman wont touch the hands.He also does not kiss nor walks hand in hand in the street, but is very sexual, talking sex and wanting anal sex as well.What is going on here . he says he is not capable of loving.Everything he interprets as sexual, if I touch his arm or caress him in a manner that is not sexual, but affective, he will interpret I want to go to bed and want sex. The first time we went to the cinema we held hands next day he asked me for time away from each other because he thought we were going too fast, however before that he wanted to sleep with me (I said no)and that was not too fast in his mind. It seems to me that what he thought was fast was the part of 'affection', what he is afraid of. He said he does not kiss because kisses are emotional and he does not want to get involved with anybody not even me (whom he likes a lot). After that we did have a sexual life that was also very loving, but he continued not able to kiss, sometimes including hands, sometimes not, and asking me to never touch him above the neck. Do you think he has mental issues, emotional issues or sexual issues, and please tell me what you think about the kink part of it all. He is not young and I was his fourth relationship, he cannot keep a relationship. I dont really know what went wrong in the other relationships, but some women he was with put him out of the house, the first one he cheated on. I know what you are thinking, what a jerk, I think he might be Bipolar and also love him to bits and wish he would get treatment for all this. Is it normal to want kinky sex and think that loving sex with someone you love is not really satisfactory. He says he sometimes feels that he is having sex with his sister (with me) , this because Im someone he really likes, respects and feels afraid to hurt, in his own words, Im not a easy woman and he does not feel so turned on by me anymore. I do all I can in bed, having been reading books to please him, give him bjobs and really love having sex with him, however his attitude is getting me down. He even compared me with someone else he had sex and said she was a loose woman and he prefered her than me , she knew more. This is so upsetting, I love him, we have been together for a long time, but Im starting to think that he has some fundamental flaws. Please please tell me what you think.
