Ive been able to masturebate and reach erection for a long time time but recently I've stopped reaching erection. Why can't I cum anymore?
When you was masterbating did you do it a lot of times, and daily? It sounds like you have to give yourself some resting time. It can happen that you have just over done it. Us guys have a way of wanting to do it so much, we need to let our systems catch up. Hopefully this will help you out some.
