If you're kissless past a certain point there's no way back. It's even worse than just being a regular verj. Cos at least your inexperience in the shagging department can be masked or overlooked in some way.
But if you don't know how to kiss by like about roughly 30 and over. Man you're in some deep close to irrecoverable shit.
Thankfully I don't think it's a fate that has befallen too many people as they have at least had 1 kiss by their 30s, even if nothing else.
And before you ask, yes, I am a kissless loser myself. Idgaf admitting it. I know it's been over for me, miles ago.
(Won't lie tho... the kiss thing hurts, it's actually my favourite part of pornos, as it's more intimate - but I also noticed a lot a LOT of pornos always cut that part out or edit skip it quickly to another shot.)
