Interesting topic.
I'm not really sure how many women I've been with but I'm guessing conservatively probably 120+. I'm 57 yo, been sexually active since I was 13, I've been married once and that was for less than a year. I've taken care of myself for the most part and I'm told by my gf that I have the confidence of a man with a big dick, and I'm considered good looking (by most anyway lol). I've run my own business's most of my life so I've had the opportunity to pursue sex when I wanted. For the most part my sex life has been a lot of fun with a few F'd up instance's.
As I mentioned on the intro thread, when I was younger I was just a bit over 5". I can think of a couple of women who we're a bit disappointed and didn't have me back for seconds. But it was after some medication I took in my 40's reduced my hard length to just under 4" that I began to get some rejection. After the size reduction I got a chance to date a cute blond I'd known socially for many years. On the 3rd date we were kissing in her driveway at the end of the evening and I thought she'd invite me inside. As we kissed my now less than 4"' boner happened to press against her leg. She drew back, pointed at my small bulge and said "And what are we going to do with that!?" then she turned and walked in her house and wouldn't go out with me again.
As I also mentioned in the intro thread shortly after we met I noticed my gf just was NOT getting off on my now reduced meat. After much coaxing and cajoling I got her sexual history out of her. Her first real BF had a very impressive big boner. Over 9" and fat and she'd had several lover's with BIG D's, and that has "set her clock" sexually, so to speak. Although she denies being a size Queen, it was only after we got some large penis extensions and dildo's did she really start to have good orgasm's.
