Hey everyone, first off let me praise all of you for making such an informative and beneficient website. It really does comfort people like me to see others who have problems and know that it's ok to talk about it and seek advice. Kudos to whoever maintains this website and gives advice, very appreciated 
Me and my girlfriend have been together for 6 months and have done pretty much everything but sex. Theres no problems with me pleasing her (from what I know haha) because she orgasms and its beautiful. However, when she gives me a BJ or handjob, it takes me a LONG time to orgasm/ejaculate. Sometimes she won't even get me to an orgasm and I don't even feel that bad about it but she gets very disappointed because she wants me to share her pleasure. I love her to death for caring, therefore I am on this forum to seek answers. Why do I take so long to orgasm? I'd say 50% of the time I'll orgasm, and the only reason why I do orgasm that 50% is because we won't fool around for a week to let me build up. Also, she has bad gag reflexes so her BJ's are very limited. Any advice would be very appreciated, HELP!
Thank you 
Some guys can only orgasm thru sex and not BJs or vice versa.
Some women can only orgasm thru oral and not intercourse. Its all how people are different.
I dunno what to do about the gag reflex, I have a bad one myself.
Brandye always has a technique. Check under the Pleasing him section.
Deep Throat 101
see if that helps any
Don't worry I learned it myself too.
Try some guides at Deep Throat . It took some time for me. About 6 months. But can deepthroat my boyfriend now fully (hes about 9 inches).
Have fun!:)
