i have not been with my wife for two years and half. but when we meet i had no feelings for her and yet i was so excited to see her and i love her so much. my pennis does not behave like some one about to have sex. what really went wrong with me could this be an STD or what i am still young in my early thirties. before this i had painfullsweelings under my armpits with fever but later they disappeared after 4days this happened after i had shaved my armpits and applied deodorant. please advise me.
