My old GF got moist w/o any problems. So, never need to worry about using lubes. I just had to be considerate and not push too hard if I entered her dry. After I did, she moistening things up quickly enough.
She also previoulsy had 3 children so was loose enough for me to enter w/o causing her discomfort but she always commented on my girth (which she enjoyed).
I'm worried about having sex post-op w/my new GF because she's never had children and has not had sex in a long time. She's a widow; her husband died about 8 yrs ago.
As a result her vaginal canal is REALLY tight. Her canal grabs my index finger like those bamboo toy "Chinese finger traps." She still felt moist inside, so I don't think that will be a problem.
I measured the girth of my dick at 6" around this morning post-op (( was 5.5" around pre-op) which will be a lot for her to take. So, I think we'll need to use some lube (probably just KY) and I'll have to enter her really slow to start.
Still looking forward to that day . . .
