Sometimes the more you want a person, the more their sexual past bothers you.
As the one who’s waiting for sex (doing the noble thing), the fact that your girlfriend/boyfriend has had sex before with one or more people may start to really piss you off.
Maybe they have slept with a couple of people but only in committed relationships. If you’re a virgin who regularly dates non-virgins, then you’re going to date people who have all kinds of sexual histories.
Maybe they waited for a while but recently started having sex. Some may have balance factors, and some may be completely unbalanced with you (read: lots of torrid sexual history, compared to you).
Secretly, your anger won’t be satisfied until you’ve brought them around to your way of thinking and shamed them for the times they stepped away from it. In fact, they their past, or your plan will work and they will feel really horrible about it. If they start defending their past, it’s going to push the two of you farther apart.
Their sudden righteous anger will turn your virginity into something that you’re holding over their head; they’ll stop valuing it and respecting you for it as much.
I’m sorry for being so snippy.” Approach the discussion as if this was completely your problem, not theirs…. And now you’ve got only a faceless sea of everyone else to potentially date.
