Re: my GF is frustrated with me HELP!
You can work through this. Its not totally uncommon among us sometimes to have this going on. Not all guys can "finish" with oral sex...as good as it is. Has alot to do with stimulation etc.
About the intercourse...sometimes our penis just gets very "trained" to respond to our masturbation technique....grip, speed, overall stimulation and such. A vagina is VERY different so the "lil guy" needs to adjust to the difference. There are some things you can do that may help...first, just keep trying and don't get frustrated...and tell her this has NOTHING to do with her! Its all a guy thing...and you don't want it to get in your head...the two of them are very connected, any frustration you feel may only make this worse so be careful. Finally....everytime you masturbate (yep...normal and not a problem!) change something, if you're not using lube...add it. Change your grip..use the other hand, work things from different angles, don't use much grip at all, vary your speed, change everything you can and do this regularly....you're "re-training" your penis to respond to different types of stimulation...this may help with intercourse as well. Good luck, hope some of this helps!
