How frequently do you do it?

Try reducing the times you masturbate, that way when you’re actually masturbating it’ll feel much better.

I know this sounds easy but is actually quite hard to control, but the way I deal with it is thinking “I just wanked yesterday, if I do it again today I won’t enjoy it and it’ll feel forced and I’ll feel shit and it’ll take longer than usual to finish and I’ll waste my time” and that usually keeps me from doing the deed for more than 3 or 4 times/week.

I do get bored sometimes even at that rate, but if you do it everyday or multiple times a day then reducing it to that rate will make you appreciate each session a lot more and feel much pleasurable.
