I've never had a problem as my base girth has grown over an inch--7+ inches now.
You do have to warm them up, and I'm with you, Red, and King. I lick and suck her clit, (which drives her and me crazy) until she's nice and wet.
The thing is I also produce a tremendous amount of pre-cum. So between the two of us, we have no problem prepping her for my full length and girth.
If she had a problem with my gains from P.E., I wouldn't be here.
