I'm a guy submitting this to the women's technique section. Since this great site is about masturbation and mutual masterbation, I thought I would give the women insights into how many of us men look at sex and masturbation - we all like to know how the opposite sex thinks, right?
Men are visual: we like to see our cocks and see ourselves naked. Many of us like to see cocks spurting cum - which is why 'cum shots' are so popular in porn.
Men are more bi-sexual than they usually admit. In the heat of the moment, try rubbing his asshole as you stroke his cock and you'll likely get a good response, he'll enjoy it.
A mutual masterbation session can be just as good as having intercourse. Remember, seeing you masterbate, turns us on.
An occasional quickie hand job: give this to your man once in awhile (out of the blue, while you are fully clothed etc.) and he's yours for life. It shows you understand his need for instant eroticism and he'll repay you with loyalty and lovemaking as well.
Watch him cum. During sex I usually bring my wife to orgasm first, so that I can enjoy my own orgasm second. I prefer to lay back and masterbate while she watches or helps me stroke. I like cumming for her and my wife has discovered she likes to watch as well.
Precum and cum tastes good. Precum has almost no flavor and try sharing it with your man while giving oral. When he cums, taste his cum and share it with a wet kiss to see if he's interested in tasting his 'love juice.' In the heat of passion this is a safe way to see if he's interested, and most men are curious. The best part of 69 with my wife, is sharing what we both taste like while french kissing.
I hope these tips give you insight - let me know!
