I have been like this my whole life which is probably why I was a terrible husband. I used to do a lot of coke and it heightens your sexual desires by 1000%. I tried hitting on my wife's sisters, my hot cousin (who I swear wanted to fuck just as much as I did) and a whole bunch of other women. For the most part it wasn't very hard to get women to do things that they aren't supposed to do (like my wife's friends). There's just something hot and taboo about it. But on the other hand the ones who denied my advances...why did I become consumed with trying to get them to give in ? Even today as a single father of 2 if I am turned down by someone for any reason I become consumed with getting them to change their minds. I guess it's an ego thing...or maybe an acceptance thing. Anyone else like this ?
Once a goal has been set, as in this case fucking other women the OP is familiar with that have said no, the human will work towards that goal learning the successful steps along the way. The human becomes elated at accomplishment of the goal. Once the goal is achieved the human feels the need to improve on that achievement. The human has learned the goal can be made and how to do it. So now that the human has learned how to obtain the goal, usually through failures, the human will repeat the successful steps with another subject. In this case the OP learned how to bed the first of the spouses friends and now sets sights on others. He's not a terrible husband but a curious human whose goal is fucking women who reject his advances at the onset. Why does he do this? Because of the elation he felt upon achieving his goal the very first time and subsequent times thereafter. It's not an ego trip but an emotional satisfaction scenario. I'm much the same way. I want to have sex. My spouse cannot anymore. My only option beyond masturbation was with other women. The first time I stepped outside the marriage I was elated with the outcome. So much so I continued with other women. I'm not terrible for taking care of my emotional needs as long as no harm comes to anyone. BTW, my spouse knows and understands my need for sex and mating with women.
