Is it normal for a boy to want to make out with his uncle?

I'm in my 50's now and my uncle is long since deceased but from the age of 12 through my college years I wanted to be sexually intimate with my married uncle! When I was at their house I would go get a pair of his underwear out of the clothes hamper and sniff the crotch of his briefs to smell his manly scent and then I would get naked and put his underwear on and masturbate fantasizing about his naked body! Nothing ever happened with my uncle and I but 40 years later I am still turned on by the thought of having sex with my uncle .
