Why are you of the opinion/under the impression that lack of sex is the same as being a loser?
I lost my virginity at the age of 20, three years ago. Not because I was "saving" myself, but because I'm not interested in randomly having sex with random anyone (I had multiple opportunities for casual sex), but having sex as a way of expressing my emotions for someone. I might as well go jack off if all I wanted was just sex, in my opinion.
Just because one might have higher standards than just wanting to shove ones cock into random human in order to not having to "feel ashamed" because of the "ZOMG I CAN'T EVEN GET A GIRL/GUY TO FUCK ME! I AM WORTHLESS WITHOUT GIRLS/GUYS" mentality so many adhere to like sheep... It doesn't mean one is a loser.
By this I am not stating that people who have one-night stands are in any way pathetic nor pitiful. If people have consensual sex on mutually agreed terms and nothing more, because they want to have sex - huzzah for them. Consensual sex is good. It's the people who have sex for the sake of not being a virgin any more that irks me.
