Hello guys, I am being friends (others think we are a couple, but we don't have a label) with a girl that is a very good as a person. We share same dreams and she is supporting me in any way and will follow me wherever my life path will take. She just graduated from masters and landed in a very good job, similar to me with high life ambitions. I would say her personality and attitude is the one I want in person as for the future wife. However, the sex for me with her is not fulfiling, although she accepts and fulfils any fantasy I want. Everything would be amazing but there is something strange with me. I treat almost every woman as a sex object. Sometimes I hang out with random girls with zero ambitions (and even not the best in look) just because I want to fulfil my sexual fantasies and then ditch them. I have done that and I feel empty after I did this. I do know that it's completely bad. It ruins my days and productivity as I think constantly about other women. I am trying to figure out why my brain or emotions works this way. Usually, for the humans the things you can't get you want the most, perhaps the girl I am seeing gives me everything and that makes my life easier and boring? Or it's just my sex drive, I am only 25. I am a healthy guy who doesn't drink/smoke and do sports. What is your experience or suggestions?
