Why can't i go all the way?

Aww Im glad you met a nice woman, maybe your feeling pressure of not being able to come, that you actually dont, maybe in the bedroom you could feel sometimes under pressure to please her, experience sometimes helps but its not always essential, drink does limit what you can do in the bedroom sometimes, but im not sure about your tablets affecting anything, maybe next time with ur woman, take things slow, and have lots of , if you still cant come id advise that you visit a GP as embarrased as you might feel. I hope this helps :)
