I think a couple of us have kind of hijacked this thread. I never answered the original question but I will now. Given that medical professionals all say the normal human range is 3-9" I would say that much less than 3" would be where the problem would start.
I, like Cthulhu, am a bit insecure about things. In my case not just penis size. I know I am average and it should not be a problem. I just don't see where I am much of anything that would attract a woman, or a man either if I was to be gay. I am sure most women would accept average even if they want bigger. You don't give your age, so I won't ask, but I doubt I could find an inexperienced woman at my age.
I really don't think size matters much as I worked with a guy who claimed to 4.75" and he was an awful woman chaser. He even said a few cuss words when had a discussion about size and I told him I was 1.5" thick. I thought 1.5" thick was average or even a low averge at that time. So he being a big woman chaser tells me it must not matter too much. He was much younger than me at 26 and he always went for the youngest legal women too. He hung around in the college crowd bars and such. Maybe that does say a bit for inexperience.
Aplus, yes, I know this is LPSG not SPSG.
I have never joined but have read some on a couple of "small support" forums. From what I have read I would not be welcome there at all. Some of them show anger toward those who are average. I joined here for the open camaraderie and honest
discussion. I have not found this anywhere else on the net so far. I really didn't join for support or justification. I will take any support I get, though.
I have read some on other sex discussion boards and they seem to be mostly propagated by teenagers and I can't get much out if that.
