Im sorry to be the boring one, and I hate saying this, but for me good sex isn't about the position. Or where its done. To me it is all about focus. All about being in the exact same place mentally and spiritually as well as just physically with your partner.
Having sex outside or some place daring would get my heart racing. Just for all the wrong reasons. I dont need a way out place to make my heart beat over the person I choose to share my deepest feelings with, and the extra stimuli would just serve to distract me from that person.
I think that just plain old vanilla sex in a place that has no outside distractions and allows me to concentrate 100 percent on the other person is the best for me.
The more I feel focused on a partner, and the more I can concentrate on them; their heartbeat, their breathing, their skin, their warmth, their reactions, their needs, and their feelings all being in sync with mine, is more important than any position.
To me, if I can attain that closeness and transcend it into that oneness of two human beings sharing the ultimate in communication then it doesn't matter if Im on the roof or have her legs wrapped around my ears. Straight out missionary position is mind-blowing.
As for advice on actual positions. I would suggest anyone wanting to spice their lovelife up look into tantric sex. I wish every man and woman in the world practiced it.
Oh man. What a world it would be then.
Well one can dream cant they?
Cold shower time.
