I can make myself orgasm within 5 minutes by rubbing my clit when I want, but when I'm with my boyfriend he can rub it for 30 minutes and nothing will happen. Sometimes I can't even orgasm over phone sex. what is wrong with me! My boyfriend does all the right things and it feel amazing, I just can't get off!
It takes the perfect storm to orgasm, especially with someone else. You KNOW what you like and your body responds to you. I assume you've been masturbating for longer than you've been with your boyfriend. Your body has to find that perfect storm with him involved that allows you to relax enough to cum. Be open with him and guide him. Give him instructions and tell him exactly what to do to make you orgasm. It may take something different than what you do for yourself. I'm the same way!
