Every teenage boy has them, but I'm coming up to 20 this year and cannot control them at all.
Kissing with my partner sets me off, straight away semi chub.
On a serious note though, is there any way to try and 'calm down'. Obviously its not a bad sign as I wont struggle to get one when the time arises (which it has, so no 'its because you're a virgin' comments) but like I said above even the slightest thing, even cuddling, can trigger them?
One thing I thought might hinder this is that I do masturbate quite often, probably twice a day? Its a horrible ****ing habit.
Any other suggestions/methods to combat this?
