Well no, not really.
But as Pixies resident slut -little person, I have a few cents worth to add to the subject.
(having had a lot of shower sex with both sexes)
Men, please turn the water pressure down a bit.
A nice warm, softly falling rain is perfect. NOT A DRIVING thunderstorm, **glub glub glub***.
Also, try running a few inches of water in the tub and sitting in it while your love goes down on you, the shower running. I love to be in a little shallow water, crouched on all fours, as I go down on my date, the water on my back and rear feel so sensual. It is easier on my knees too.
In general combining tub sex with shower sex is very nice.
Sitting in your partner's lap face to face, is warm water, as a soft warm rain falls... ohhyessssssssss.
I agree that oral is the best shower sex. Most good artificial lubes wash away in the running warm water. My natural lube works well enough, but height and size problems limit the postions I can try.
Suspended up in the air, my arms and legs wrapped around him, my back and ass pressed hard against the tile as he makes love to me is WONDERFUL, but ever since I read about the couple who fell through the hotel room wall, into the adjacent hotel room shower in mid orgasm, well, I can't relax enough to really enjoy it as much as I used to.
DO NOT try intercourse sitting on the edge of the tub.
Slipping and falling is inevitable.
Anal is possible in the shower, just be careful.(Mmmmmmmmmmmmm)
By the way, my exhibitionistic streak is fed by the knowledge that in hotel rooms, everything in done in the shower is heard next door, in amazing detail!!!!
Sex between two women in the shower is very, very special. Showers lend themselves perectly to long periods of mutual touching, stroking. licking, and probing.

Clean sex thoughts, (well, at least well scrubbed)
