Let's talk about sex...

Okay, we all know that sexual intercourse burns calories...sometimes even a LOT of calories. So why is it that none of these logging sites list sex as an exercise option (at least MFP, FitBit, and Endomondo don't).

The way I see it, the VAST majority of users of MFP, Fitbit, et al. are grown adults who are perfectly capable of seeing the word sex in a list of exercises without getting offended. And with children being taught sex-ed as early as 5th grade these days, is it REALLY that unacceptable for any child users to see the word? It's not like they'd be exposed to any graphical definitions or anything. Heck, even the most uptight individuals still HAVE sex, don't they? Well, most of them, anyway.

Here are the metabolic equivalents (METS) for sex and other common activities, from
http://soltherapy.wordpress.com/2008/03/25/sex-for-better-health/
-- having SEX with partner = 5 METS
-- having SEX with mistress = 9 METS
-- playing basketball = 9 METS
-- playing tennis = 6 METS
-- skiing = 8 METS
-- walking 1mile = 2.3 METS
-- walking 2miles = 3.1 METS
-- walking 3miles = 4.3 MET

So what's the big deal?

I propose that MFP add three activities for sex in it's cardiovascular exercise database:
-- Sexual Intercourse (light)
-- Sexual Intercourse (moderate)
-- Sexual Intercourse (vigorous)

Would that really be so offensive? What are your thoughts on the matter?
