To express erotic desire.
To experience beauty
To boost our self esteem
To be polite
To establish and maintain intimacy.
Intimacy: that feeling of intense closeness, of opening not only your body but your soul, is essential for starting and maintaining a romantic relationship, the only way to distinguish friends and roommates from lovers.
These are sexual acts rated on a scale of 1 (least intimate) to 10 (most intimate).
To determine the intimacy of your sex life, score yourself for each of these acts that you engaged in with a partner during the last week, then divide by the number of sessions.
For instance, if you had five sessions last week, twice as as an anal top, three times as an oral bottom, three times as an oral top, and and one mutual masturbation, your score is 6.0
But, if you had five sessions last week, all involving kissing, plus twice as an anal bottom and three times as an oral bottom, your score is 12.8.
Note: They are rated on intimacy only, not on other ways to judge a sexual act, such as skill required, degree of erotic stimulation provided, and facility at producing an orgasm.
Plus you have to concentrate on proper technique. If you are big, how to minimize the pain? If you are small, how to keep from popping out at every thrust. 2 points
Anal Bottom. The same problem as with topping -- facing the wrong way, or you can't see much. But the pain and sense of risk work to increase the intimacy. 4 points
BDSM Top. BDSM requires even more preparation and equipment than anal, but it's not just a matter of plowing in. You have to pay careful attention to the bottom's reactions, and modify your actions accordingly. 5 points.
Frottage (through the clothes): 3 points.
Interfemoral (naked): 7 points.
Kissing. So intimate that some guys won't do it at all, and others, only with a romantic partner. 10 points.
And you have to be very aware to your partner's response to move toward a simultaneous orgasm. Very intimate. 7 points
Oral Bottom. Not very intimate at all. Most guys will go down on anyone who offers, regardless of face, physique, or personality -- a penis is a penis, and beneath the belt they're all the same. You can even go down on a disembodied penis, through a glory hole or in a dark room, and have no idea who he is or what he looks like.
And the thrusting requires so much concentration, so much attention to technique and breath control, that you don't have much time left to establish emotional intimacy. 2 points
Oral Top. A little more intimate. Just as with oral bottoms, most guys will drop their pants for anyone who asks (as long as they are male and over 18) -- a mouth is a mouth. But putting your penis into a position where you could get bit requires a minimum of trust, and at least you can look at at your partner. 4 points
