Ok we’re on the same page that it’s dumb. Let me see if I can figure any internal logic to it:

I guess there’s an element of penis insecurity to it. That is to say, if a woman sleeps with a lot of men, some of those men will have big dicks. Those men will “ruin” her vagina.

Now obviously this isn’t true since that’s not how vaginas work, but if youre incel brained and concerned about “chads” stealing all the women and you not being able to compete then on an emotional level it might *feel* true.
