dear friend, thank you for your advices and suggestions. i am so touched.
i would like to let you know more about my situation. there is nothing my OM can do that my H couldn't. tell you something a little funny. i expected my OM's cock to be bigger ( because he is taller), but it is a little smaller to my surprise ( and a little disappointment, heehee...). when he is inside me, it doesn't even feel as good as my H's. but because of the intense emotional connection, i just love to be intimate with him. is really nothing to do with technique, my OM is not even as good as your H i think.
as for my H, he is not a selfish guy. he always wants foreplay and to satisfy me, i am the one who can't be bothered because i am totally not interested in him. when i first knew him, i really like him a lot, ok, not as much as my OM, but you see, at that time, my other choices are worse. also, the way he loves me touches me that time, that's why i married him.
i will try to improve things, is not easy i must say as i am now so blinded by my OM. my OM is away for a few weeks, so i am actually glad that i can take a break emotionally and think things through. i am also reading the crazymom thread as suggested by others to see what i can learn from there. thanks again.
