I will add that all the girls and woman I've had sex with since my cock has grown to 7.25 inches in girth have all loved it. Allot of it depends on two factors.
#1 How you enter and perform using the tool i.e I go slow with whores at first but with my lovers I lick their pussy to death for ages and than enter, no problems than. I take it easy with my thrusts to start with and build it up and judge from her reactions how she likes it.
#2 How experienced she is. I have had sex with 16 and 17 year olds which is legal here in the UK and some couldnt even get my cock head in their mouth and the odd one bit my dick. So they hadnt had many cock. Yet again I've had 21 year olds who nearly sucked the entire thing down ... its a major factor, how experienced the woman is and I suppose also how horny she is and willing to adapt ... most woman when horny will adapt and take a thicker cock and I know that all of them, even the shy ones played with it for ages and than when they got confident couldnt keep off it.
The whole point is, that a thicker cock can still have a good love life .. myn is and in the near future I will aim to pack more girth on if I can as I belive girth is allot more special over length ... once you get to say 7.5 to 8 inches length than I think enough is enough ... but saying that I suppose 6 inches girth could be said as being the same ....... lets get bigger and better.
