I'm 8x6 and have had about 30 partners, to include, as was asked Asian girls, smallest partners were in the 5'2" maybe 105-110 pound range. I also haven't seen a significant relation between pussy size and total package size. I've bottomed out badly in tall girls and not in short ones. Same with tightness. No relation IMO
I've never had a girl have a problem with girth, never a complaint. I always get plenty of complements. I've had anal w half or more w no problems. Always getting return customers
I have had a few girls who drug teeth during oral but I've been able to let them know and they have fixed themselves.
I've had a few issues w hitting cervixs and hitting them hard, especially when I was younger, now I'm more careful and work my positions more to make sure I'm hitting all the right spots.
6 is XL but not huge, condoms are a PITA, as someone else said I'm sure all the girls I've been with could have handled .5-1 more of girth.
