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.
Maybe they had sex before with one person but only a couple of times.
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).
If you let all of your hurt, anger, and sense of injustice build up inside of you, you’re going to take it out on them whether you intend to or not. You’ll get irritable and won’t tell them what’s wrong.
And maybe one day you’ll snap and call them a whore or accuse them of not taking sex seriously, etc.
