1. Bring a girl or guy back to your place to have sex. When its just getting 'good' see if you can stop IT from happening.
2. Walk up to everyone you see and ask if they would like to have sex. (i watched a guy do this at the beach and it worked)
3. Don't have a orgasm for 3 months.
4. Airless tires
