It seems that it is inappropriate to mention sex at all on a profile. (Other than women saying they don't want a hookup or one night stand).
That is, I would like to specify that a potential partner would have a medium to high libido and have a few kinks or fetishes and at least be open to talkong about it. This isn't to say I am looking for a hookup, but is seems odd to me to find out on the 6th date that your partner isn't interested in sex at all, or conversely is into some really extreme stuff you're not comfortable with.
Should a polite and well worded paragraph on sexual wants, needs, desires etc. Be seen as a taboo?
