I´m 30+ and still a virgin

I'm not a virgin but have had only a few short relationships but come across as a virgin since I'm seldom in a relationship and don't really have any sex life to brag about. The one thing I really loathe is coworkers always talk about sex and establish a pecking order based on sexual prowess, experience and orientation. If you don't talk about sex, word spreads quickly through the grapevine, and no one wants to be stuck alone with you in the office since that's about all they talk about, so they leave you in the trenches instead of promoting you to jobs with more social interaction. I think it even factors in the hiring process for small businesses. They want to know if you're married with children, aka "normal". This may be more of an issue for men though. I've worked for many companies and this is true for a majority of them, especially after you've reached age 30.
