Since I started I have always used lube, in fact we all do in the way of olive oil if your in the kitchen.coconut oil is good as it lasts with lots of slip, there lots you can try.
Never very big but at 73, sometimes hard to even find it. Totally withdrawn flacid on arising in morning. Hell to get old.
My cock is probably five inches hard, maybe five and a half on a good day. I am my girlfriend’s bottom. She has a lovely seven and a half inches.
Pretty sure I answered this question a long time ago. But what the hell, 7" long, 5.75" around. Circumcised, veiny, with a ginger bush.
