If you're insecure about your size, don't be. That is a universal male problem, no matter how big or small his penis is. I just had a quick look at your photos and your penis is just fine. Indeed, it's better than just fine, it's lovely. You've got a nice straight shaft, a well shaped head and good proportion between head size and shaft length and diameter. I'm a mature gay man who has had a very active sex life so I've been up close and personal with a few thousand penises and I've rarely seen one as nice as yours. You have a great dick, enjoy it.
