First of all, I'm a woman. Secondly, I just want to let you know that Orajel (and Baby Orajel) has many uses. I've used Baby Orajel to numb or relax my throat for the purposes of oral sex, and it doesn't numb or rub off on my partner.
Also, for those that are having trouble reaching their big finish, you're putting on way too much and not in the right spot. You still want to keep some of that sensitivity so don't put it on the head. Put a small amount (of whatever kind of Orajel of your choosing) on the underside of your penis, just under the head and down the shaft, and for good measure just underneath the head. Aside from the head of your penis, those areas are the most sensitive.
