Do you know something, I am not sure when my penis reached its full length, I think it could have been as early as 14 as the boys in my class compared mine to a grown man, I had one the the largest penises the boys said they had ever seen. The thing is if that was the case not being fully grown but having a man sized penis made it look extra large. By the time I was 17 the rest of my body was fully grown, that made my penis more in proportion with the rest of me, just the same size 7" but more in proportion to my body. I have always felt comfortable with my penis, it is on the large side of your 5 to 7" average, but as it is not over big it pleased my wife no end when we were making love frequently during our marriage.
Penis size is just a mind game that men play with themselves and other men -- and now women are attempting to play it (for whatever reasons they have, none of them usually have anything to do with the actual size of your penis).
Having a smaller penis is only an issue if you're stuck with a woman who has a huge vagina. The real issue is maintaining a good, hard erection...which becomes more a concern with age. But then, it's a completely normal part of the aging process.
So any woman who complains about your penis size is either trying to be cruel because she's mad about you over something else, or is in denial about her over-sized vagina...or just doesn't realize that the real problem for her is she'd like your penis to be harder...and that's a reflection on her, too, when you think about it.
That is absolutely correct jolly rodger, no women should complain about the size of her boyfriend/husbands penis, however, they might be a little concerned about the size of it. When my girlfriend first saw mine the thought in her own words that her boyfriends penis was "enormous" She had never seen a man naked before, let alone a erect penis. I realized that I had an above average penis when I was 14 and at school. I had been introduced to a boy who also had a large penis several months before that, at the back of the bike sheds. One time one of the boys found a porno magazine lying around somewhere. When he opened it, there were pictures of nude women, however, at the back of this magazine there were pictures of men with erect penises, wow the boys said, look at the size of the penises on those men, I thought to myself, so what, my penis is like that and thought nothing more about it. Some time later all the boys wanted to compare their penises with each other and see if any boy had one the size of the men in the magazine which we all had looked at, so one by one we boys took out their erect penises to compare each others. I looked around at them and thought that most of the boys penises were quite small and not as big as mine, so my turn came, OMG they shouted, ALs is a big as the men in the magazine, it was only then that I realized that I had a larger than average penis, it made me feel good. There was a film star at that time who was reputated to have a penis as big as I had, I don't know if that was true, however, they started to give me his nickname because of the size of my penis. As I say many years later my girlfriend thought also that I had a large penis and measured it with a measuring tape, it was bone hard, I had never seen it as big, females have the magic touch to make a mans penis bigger than he himself can, I read that somewhere else on the Internet. She measured it as 9" long by 5 and a half inches in circumference. I actually thought my penis was 7" long, it did not matter, as she went around telling her friends that her boyfriends penis was that length, I just kept quiet. I am actually quiet proud of my penis, it is a little above the average in both length, thickness and is on the hairy than average side, it is within the accepted thickness/length, I had no trouble making love to that girl who I married and had plenty of sex without any problems hurting her, I just took it gently, she loved it, she said it was just the correct size for her vagina and everything was OK, I made her pregnant 4 times without any problems.
