It's called frustration.....
You know whats weird. You know that no matter what you do, your boyfriend will get off....in less than 5 minutes. You take around 20 to warm up. If you can make it last longer, he will love it and you even more! As a man, I say foreplay is the best and I like to drag it out.. It is so good. You are cheating him and you out of a very good time.
So, don't get him off so quick. Make it last an hour or more. Use your hands and some lube to excite him. Him you. As you're moving slow, compliment his manhood. Whisper love words in his ear. If he is about to pop, slow way down till he gets soft. Bring him back up several times.Pop him off or then have intercourse. It all feels good.
You could also try doing it in different places , during odd parts of the day, with soft music or soft lights,sexy lingerie, on a sheet on the couch,watching soft p 0 r n, in a chair, use your imagination, but make it last.. L O N G.
Leaning back and try having him turn ONLY you on for an hour or more, then he lies back and you do him. Next time, try mutual self-gratification....but do him SLOW. Really take your time and talking it out about what you or he wants to do is all part of the relationship.Tell him your ideas...he will love it...it shows him that you are very interested in sex. Find out his ideas.
Have sex only when you have time. Start having sex thoughts at lunch. A twinkle in the eye, suggestive words, etc. Try it and you and he will both be happy. Please let us know how it works..
