OK all, here is my problem: Whenever me and my g/f get "intimate" I never seem to last that long when constant attention is given to my penis. Either by me or her. Also when I am "done" I get really tired and am not interested in sexual activity nor can I really enjoy another orgasm. The second one last longer ofcourse but I do not really enjoy it . Is there anything I can do to help with anything? Eat something, practice something (myself or with g/f), anything? Thanks for any and all help all.
