I can't give you a figure. I tried a few years ago to come up with one but failed. Remember, I had my first when I was only ten years old. I'm sure that it would be in the high triple digits - maybe more.
My reason for posting to this question is that I was reminded of a time when I thought my big dick was going to cause my early demise. I had been in Miami Beach for three months at an Officer Training School where there was no time or opportunity for my (then) favorite pastime. After graduation frrom the above School I was ordered to Kearns, Utah, which is near Salt Lake City. The first night there I went to a local dance hall and met a cute little girl (about 5' tall) and took her to my motel room for some good Scotch whiskey for which she had expressed an affection. It wasn't long before we were naked in bed where I surprised her with not only the size of my equipment but by performing three times in fairly close order. Starting from that point we wound up every evening in the motel for a repeat but usually only once or twice a night. At the end of the first week she invited me to move to her family home which she shared with her two sisters - one two years older and one nearly two years younger who was quite pregnant. I moved in with her but to maintain a look of leasee I had a bed in a separte room (upstairs) from her room since her Dad came home on week-ends. Without a lot of explanation I eventually was spending bed time with not only Helen but also her two sisters. I was there for just a month when I was ordered to California to await transportation overseas.
Needless to say I was in a weakened condition (and had a terrible cold) when I left Utah. After the trip to Calif. and to Sick Call I was back in shape. Met a beautiful gal with monumental tits. Went to San Fran with her where we screwed for the first time but back in Pittsburg, CA., we got with it every night until I was assigned to ship out.
That was two weeks after the trip to Frisco.
I boarded ship one afternoon and our first "boat drill' was conducted at dawn the next morning. I was surprised to find that there were a group of Red Cross Hostesses aboard who were bound for Australia. Three of them were assigned to the same life boat as I. I struck up a conversation with the hottest looking one, spent most of the rest of that day with her and fucked her on a deck chair that night. She had a state room with another gal and there was also an attached bathroom and toilet. She soon made arrangements with her roomy to alternate nights with us to have the place to ourselves until midnight. Next night we would use it after midnight. The other gal had a boyfriend by then.
This arrangement continued for the whole cruise (to the Solomon Islands) which was for 30 days during which we screwed every single night - usually twice because she was such a hog about my oversized joint. When we parted company (at last) I felt certain that I was fucked out for life.
I was wrong!!
