If you're going to put on a condom with your mouth, the first thing you need to do is choose the right condom. It's much harder to do this if your tongue has gone numb from nonoxynol-9. Having gotten that hurdle out of the way, the steps are as follows:
- Unroll the condom slightly so that there is enough room for you to grasp the tip firmly between your tongue and the roof of your mouth.
- Put the condom in your mouth, making sure it is not inside out and being careful not to bite it or tear it with your teeth.
- Holding the tip of the condom against the roof of your mouth (or the back of your front teeth), so that the air is pushed out of it, let the opening of the condom come out in front of your lips.
- Use your lips to guide the condom onto the tip of your partner's penis, and slowly push down with your lips and/or hands.
