My experience so far:
Gemini: Very speedy in the bedroom in more ways than one. Easy to mould to suit your needs. Not at all passionate.
Virgo: Loving, caring, take their time. Not aggressive at all. Perfectionists in the bedroom as well as out.
Scorpio: Insatiable appetite (don't we know it). Tremendously passionate lovers. Perhaps care more about their sexual appetite than their partner's needs.
Capricorn: More on the dominant side. Likes to take the lead. Very good sex but quite bland.
Aquarius: What can I say? Great sex. Definitely make you want to come back for more. Nothing extremely special about them though.
I'm torn between whether the best sex I've ever had was with a Virgo or a Scorpio.
