5 inches here as well as pretty pathetic girth. I suffer a bit from anorgasmia (can't nut) sometimes, I think its mostly related to age now and being a bit low T. Feels like a pointless ability, I would much rather rock a chicks world for 5 minutes with a big dong than be able to go for 40 and have her barely feel anything.
With that being said, I am married and sex life is actually decent. Wife had very little experience prior to me, so she basically doesn't know what she is missing. Can't make her orgasm from just PIV, which women claim is just something most women can't do, they need clit stimulation. To me it sounds like most men just don't have big enough dongs to stretch the vag out sufficiently. She has stroke tier orgasms from penetration and a vibrator though, so thats something at least.
I mostly try to be grateful for not having an even smaller dick, e.g. 3 inches.
