Hello, I see your problem.
I used to have trouble having an orgasm outside.
Now I can have them all the time. You just need to relax,
and find a a nice boyfreind who will take his time
and look for the right place to use his hands. You need a private place for sex so you can relax. Marijuana is also REALLY good for sex. Your body will become sensative if you smoke some before sex. OR try drinking one beer before sex to relax. Keep practicing!
Try using a "G-Spot" dildo(plastic penis)! There SOOO GOOD! You can go to a sex store in Vancouver - there always really nice people!
