Not being able to stop lusting over other people, while being in a relationship

Hello everyone, I am over 18 years old male and I am having a problem of lusting over other people, even though I am in a relationship. I am also masturbating too much (~once a day) and I really think it's enough and I want to stop.I try my best, but bad thoughts always come to my head. I watch a video, look a movie or even a commercial, walking a street, just basically nearly at every opportunity if I see someone attractive I lust over, having bad thoughts. About the masturbating, I thought that stopping it would also calm the thoughts, but no. I have been doing it for a long time, since my teen years, but the biggest period of time of me not doing it was 3 weeks. Then I would think "of, gj me, I spent 3 weeks not doing it so I will do it now to ease myself and then extend the period even more". But no, it would just revert to being frequent again. I really can't take it anymore. If you wonder why I do masturbate, well, because it's the activity that really relieves me from stress and calms me down. But only for that moment, because in the long run, I feel tainted and empty. I kinda have almost a split personality in terms of that, because on the way home I would think "no more, it's enough", but when I actually come back I am like "Just one more time, I've been having a tough time".. I just want to stop it, more than anything. Both the lusting and frequent masturbation. Help me!

Your wanking isn't a problem believe me. What male or even female doesn't? (yes varying degress) but it's a natural thing and it should not affect you. The lusting again at your age is normal, curbing it without acting on it is more difficult. You don't tell us about your relations, therefore approaches with them and your friends M or F. You are a standard issue 18 male.

I don't think anything is wrong with u sweetheart. But from what u wrote it sounds like your really bothered by it. So maybe u can seek help from a therapist. But as for my thoughts on it I don't feel like your doing any harm by masturbating to relieve stress. It's actually quite normal.

Don't feel bad there is nothing wrong with you, you are totally normal.
