PE helped me last longer.

So i’ve been doing PE for 3 months now. I’ve made tremendous gains , In my stretching routine I mainly focus on kegel’s and reverse kegel’s . I think now after 3 months I feel like I last longer while i masturbate it usually used to take me 3-5 min of continuous simulation to make me cum , but now I need minimum of 10-15 min to cum now masturbation for me has become a pain in the hand. Well any way’s I don’t know how long I will last in bed I’m a virgin .
