How could that possibly screw him up? This wouldve never even came to light had the girl not cut him off from the snatch and the guy started harassing her about it plus threating self harm if she didnt hand over that kitty.I can’t imagine this kids perspective on sex now. Could be OK but I can see how it may screw him up for the future as well.
Sounds like the only way it could screw him up is he aint gonna find another girl hot as her to preform the worm with.
