Again, this statement "guys are usually way more interested in cock size than a girl is" is true generally, but makes me wonder how carefully you've been reading these forums. There are certainly women who find penis size a turn-on. With regards to the original poster on this thread, if I might take a stab at this from a psychological perspective: She had an interesting thread recently about how she never gave a lot of thought to size but now she's dating a guy who's big and she loves it. She felt guilty about being into his size and a lot of people on this site basically told her to relax and enjoy it. So I wonder if measuring the bf's cock was part of her telling herself it's OK to care about size.
But as for the statement that most women don't care much about size, true. But some women do, and this is the LPSG for god's sake. Our women are a little different I think...
