San Francisco, you dirty birdies.

In a study by Trojan condoms about sexual activity and satisfaction, San Francisco ranked third in the nation among the company's top markets.

Trojan released the national study on Thursday, comparing cities, age groups and gender from coast to coast. But even though San Francisco steamed up the survey, it couldn't quite bring the heat like Miami, the highest ranking city on the list.

Compared to the top spots, San Francisco was rather discreet in the sack, reporting the shortest sex sessions and the lowest number of participants open to using a vibrator. (For shame!)

However, while it seems our exploits might be few and far between (120 per year--31 times lower than the national average), we aim for quality over quantity: San Franciscans reported the highest level of satisfaction and were the least likely to fake an orgasm.

Here's a summary of how SF measured up:

Lifetime sex partners: 21
Daily thoughts about sex: 5
Sense of sexual adventure: 59 percent
Open to using a vibrator: 66 percent (least)
Level of satisfaction: 65 (highest)
Faked an orgasm: 31 percent (least)
Number of sessions per year: 120
How long it lasts: 31 minutes (shortest)
