depends on the mood
sweet and sensual? most would probably say R&B but id rather go with some slower tempo, rrrrreally deep house to prog tech/house. stuff thatsa bit more ambient than not. ambient trance can be ok but sometimes its wierd. some A Perfect Circle songs work here.
deftones rules too
but for some real hard nasty rompage id go with some really hard, more up tempo techno. of course with the music so fucking loud it almost drowns out our noise.
ministry? prodigy? NIN? all the more harder/sped up tracks

i find that sort of music to be quite sexual in a very odd way.
dated a girl that was really into jazz, and tell ya what jazz is some hot music to fuck to.
actually i had sex to motorhead blaring out of my computer once. it was fucking awesome. provided you got a real rock and roll girl, it just made it absolutely primal.
but personally, the only music id like to hear when having sex is a woman's voice. id rather do it in silence

SLAYER!!!!!
No but seriously my girl loves getting down to 'White Pony' and it's sweet because Deftones are one of my favorite bands.
as much as i loooove metal, i doubt i could have sex to it, unless i was doing it to be funny and was really wasted. metal is possibly the most unsexual music i know of, save for some forms of black metal (but thats just for wierdo vampire sex). sex to slayer would be like having sex on top of a bed of nails, it really just doesn't coincide with a sexual mood imo.
SEX, MURDER, ART \m/ !!!!!
but yeah when i mentioned deftones, i totally ment white pony. best deftones sex playlist goes:
ALL of around the fur except for tacks 1, 5, and 9 (usually cut 10 out because of the 10 minutes of silence at the end, although 'MX' is a very sexual song imo, especially with the chicks voice she makes me hot)
and then all of white pony except for mini magot, and track 3. i eliminate track 4 out of personal preference. track 2, "Digital Bath" may be one of the best lovemaking songs of all time, with the exception of the meaning behind the lyrics
and then add from the self titled album - track 2, track 3, track 5, and track 7.
then smoke a shitload of herb and start making out and press play...
