Oh yeah, Mars is a biggie when it comes to Sex drive.
I give the sex drive to Mars, myself 
I know that's the norm - but my Mars is in Cancer conjunct Saturn, and both are Retrograde, and form part of lots of T-squares inc opposing my Venus/Vesta/Sun conjunction, so I can only imagine my BML is responsible for my high sex drive!
My Mars does sextile my Taurus Moon and Pars Fortuna, but those are the only benign aspects to it. It squares my Chiron/ and Jupiter/Juno in Libra, as well as the opps.
I have a lot of earth in my chart - four personal planets, Asc, and several major asteroids. I wonder if that provides a strong sex drive too?
I've got an 8th house Sagittarius, with Neptune and sometimes Juno there, depending on the chart type.
But I tend to get more inwardly focused, and quieter when the Sun is in Sagittarius. I think when it moves into early Capricorn, I feel more, er, earthy. Now when the Sun is in late Cancer, and heading into Leo...that's the transit that I feel "super hot and grumpy" during. It's so annoying have a set of kitty claws, and nothing to grasp and knead them with.
I guess that makes sense, as either my Mars is in my 5th house, or it's ruled by Leo depending on the house system. And the fifth house rules playful sex I think.
I dunno. I just think it's all the Scorpio in the air. I've noticed it too. Sun is trining my Mars though
7th house. Contains most of Scorpio, though.
My 8th cusp is 1 Sag.
My 8th house is taurus... and my moon is in there, I'm pretty lusty.
But I try to control it, I have mars in virgo... with a saturn aspect. :/ I feel kind of guilty if I don't.
ETA - actually, I've noticed my sex drive gets higher when moon goes into Aries. Not sure about the sun transits though.
