[C/S]

First let me say that my wife is incredible in bed and that we have great sex together. I do also have to say that with her, you better be able to last because getting her to cum sometimes is a chore. She says that I am the only person that she has ever been with that makes her orgasm every time we have sex. She said it was very sparatic (sp) before we got together. I would love for her to be able to orgasm several times. She says that when I make her cum, that she orgasms so hard that it makes her head hurt and she is completely wiped out afterwards. Like I said, it is alot of work sometimes, so our sessions are not quick at all (even with ALOT of foreplay). I love watching her with other men, but would like to have her orgasm with them. We both agree that she does not want to orgasm with them, because she will be so "spent" that she will not want to have sex with me. Its funny (not really) because she reminds me of a man, after she orgasms, she lays there for a minute to catch her breath and then passes out. Are there any tricks/tips to help her become a multi?? Thanks
