Was my Uncle Bi or Gay?

It seems that a lot of gay men talk about being molested (although some of them don't think of it as abuse) as a child by an older relative.  The question sometimes arises if that is what caused the man to be gay.  While I don't think so, it is my belief that we are born with our sexual orientation; perhaps being gay may be somewhat genetic.

Well my uncle lived on the family farm, never married, and seemed somewhat preoccupied with sex, or at least so it seemed to my childhood naivete.  He was "known" to date women, but it always seemed that they were chasing him and he was trying to escape them.  In addition to being a farmer, he was a carpenter by trade, and he often carved objects out of wood.  One of these objects was a beautiful piece of dark wood such as walnut whittled into the shape of a very large penis -- about 10 inches long and comparably large in girth.

As a child, he often took me off on various adventures, to go fishing, boating, and camping.  On one of these trips, we went down to the local river and he suggested that we go swimming.  When I protested innocently that I did not have a bathing suit, he said that there was no one around, we didn't need suits and could just skinny dip.  Once in the water which was very cold, I was complaining and wanting to get out.  He grabbed me and pulled me close to him and asked me if I was feeling the warmth of his piss.  Nothing more than that happened.

Also I remember sleeping with him in his bed in his log cabin during the summertime.  At the time, I was an early teen-ager while he lay close to me and told a few dirty jokes.  However, again he never went any further than that and did not touch me.

After he turned 60, he developed prostate cancer and in addition to the medicines he was given, the surgeons castrated him supposedly to arrest the cancer.  One afternoon we were walking on the farm, he pulled out his dick and said watch this as he pissed a blue color resulting from the medications.  On another occasion when we were alone, he pulled down his trousers and underwear and had me feel his empty ballsack.

I have a much older male cousin who also spent many summer vacations on the farm with my uncle in earlier years before me, and I have wanted to ask him if he also had any similar gay-like experiences with my uncle.  This cousin is married and I have never had the courage to ask him.

Somehow, I believe my uncle certainly had gay tendencies, but out of respect for his sister and me, he knew where to draw the line.  I'll never know for sure.
