When guys are in a relashionship than the woman could enjoy that larger size more and seem to want more, but that to me isnt an indication that woman on average would want a larger girth for satisfaction. What that tells me, is your both loveing couple and its that which is what spurs her on with the larger size and or wanting more. Its different when your with someone you really like and indeed love, because they will accept you if your cock was 8 inches thick, if they love you they will and they will adapt to it, but thats not to say and class woman as wanting that size for them being ideal.
Ideal size, well shock size I would say is 6-6.2 inches .... that is more than enough to fill the vagina and get pleasure for you both. Woman who think that is small or not large enough, well my advice is ditch them as they are either size queens, closet size queens, sluts, loose or used to fucking monster cocks and who wants to be saddled with a cock crazed woman anyway? I dont .. I want a woman who will give me love and affection more than mess with my cock to be honest.
I've had more woman than I can remember from many nations and I have noticed they all seemed to respond best around the 6-6.25 inch range in girth but I have still had woman scream in pleasure from the girth I'm at now, but they have been either in a relashionship with me and built into that, at first they werent screaming in pleasure and also the sluts from one night stands, they are sexually active and after one thing anyhow ... sex and dont give a shit if you shove an anaconda inside, a cock is a cock to them or anysized object like that.
Something else I noticed is most woman at my size now, it started at 6.7 inches girth cant even take half of it inside them ... thats right so in most cases they can only squeeze half of inside them unless they are looser than normal and more sexually experienced perhaps, but most cant. Once I've been in a relashionship with them and they become used to it, than yea they can take more and enjoy it more but like I previously said this doesnt mean the woman wants a cock that thick ... it means that I'm makeing her FEEL great and this is less to do with penis size and MORE to do with what YOU DO such as foreplay, pillow talk, positions etc etc and I love foreplay and love to massage her all over and kiss her all over etc which gets them so horny, they dont mind the huge cock ... you see its giveing in the longrun when your with the woman you love that enables her to forget that massive member, if you have one and remember what you can offer ... what you offer as sex is moe of a phychiological sensation [is for me] than physical and woman really catch that the most.
So ideal size for most woman is allot less than us men think and once your in a loveing stable relashionship your lady will more than likely adjust to take your larger size and enjoy it, not because your bigger but because you are a good lover and show her this love ... the bigger penis is merely the attachment that brings you both together, its like one of those corridor things at the airport that passengers walk though from the airport to the plane.
