what you fantasize about and have memories of...is pefectly normal...I have a very desireable best friend and find myself very attracted to her...but, I don't find myself attracted to other women...I think it has something to do with the personal bond and friendship that she and I share...so, just keep your fantasies and your memories to yourself...it doesn't make you gay...just normal....I'm sure other men (and women) have the same thoughts and attractions but, they just keep it to themselves...I repeat...don't tell your wife.
