Is there such a thing as dick to big?!

I'm dating this guy and we haven't done anything yet but kisses and hugs, at some point I got to close to him and I could feel his 🍆, lord Jesus I thought it was his leg for a moment, I mentioned to him the next day, he confirmed it bigger than average size( he wasn't bragging or anything) my previous sex partners didn't have that size for sure.. in a bit scared to have sex with him lol what if it to big for me 😳🙄 I know the vigina adjust to different sizes but Still lol
