I don’t think so. I have hitchhikers thumb, so my thumbs do bend backwards. They don’t feel disadvantaged in terms of touching compared to my other fingers.

I’m talking about just the tip, the part you use primarily for touch, not the whole finger segment. You’d need to be missing a nail - and if you ever are missing one, you’ll be surprised how much of your sense you lose!
