it's a stupid and simple question .....I have been masturbating for years so in my opinion my nerves and mind are use to me (I don't know if i am daying it right ) I foreplay and all that....and I have an erection but when it's about that time to stick it in it goes away with and without. condom I want to have a normal erection... ¿how? ¿can a vagina sex toy can help ED so that the nerves of the Penis can get use to it?
