I have tried a few in the past and they always seem to have the reverse effect. They tend to numb the vagina more then myself. Do any of these work well, or are they just a waste of time and money
It may help to let it dry after you put it on and absorb into the skin before you start having sex so it doesn't rub off on her. Alternatively you can just start doing some exercises to last longer naturally, for example during masturbation you can bring yourself really close to orgasm then stop, then do it again.
