I thought this abstract was interesting; I don't know how it relates to adult sexual activity, but I would be willing to bet that early social responses don't change very much as the respondents age. The abstract in part:

Consistent with a traditional sexual double standard, female adolescents who reported having sex had significant decreases in peer acceptance over time, whereas male adolescents reporting the same behavior had significant increases in peer acceptance. This pattern was observed net of respondents’ own perceived friendships, further suggesting that the social responses to sex vary by gender of the sexual actor. However, findings for “making out” showed a reverse double standard, such that female adolescents reporting this behavior had increases in peer acceptance and male adolescents reporting the same behavior had decreases in peer acceptance over time. Results thus suggest that peers enforce traditional sexual scripts for both “heavy” and “light” sexual behaviors during adolescence.

I think everyone knows that girls who sleep around in school get bad reputations, but it was interesting that boys who reported making out had lower peer acceptance over time. Over time, I assume, means that they repeated this behavior, and perhaps were either seen as being in a semi-friendzone (orbiting with low level benefits) or they gave away commitment to quickly, repeatedly. If you have any guesses, please comment!
