my realisation

I was young, and had never thought of gay sex, but found myself after a session with my girlfriend walking down the street, thinking of a blow job, it was making me hard again, then I realsied I wasn't thinking of getting one, but giving one. I was now rock hard and scared. Did this mean I was gay? I spoke to her about it and she dismissed it. Later that month we were at a gay bar, she was dancing with her friend when a guy approached me, we chatted a little, I didn't even realise he was hitting on me, when the Barman told him I wasn't gay, but her with 2 girls. He retreated to his table, but when I went to the toilet, he followed. He came up beside me and appolagiesed, he was a little too close, and turned towards me, I couldn't help but look, his cock was massive. He asked if I wanted to take it in my hand, and all of a sudden the thought of giving a blow job came back, he noticed me getting harder and took me to a cubical. I took it in my hand and began to play with it, just like I would my own, but wasn't use to the size, he asked me to lick it, I did, but couldn't get my mouth around it. He had some pre cum dribbling, so I licked it up. It made me want to go on, but someone came in the toilet, it scared me, so I left.
I often think bout that night, especially when my now wife asks me how it felt to be chatted up by a gay guy, if only she knew how much I enjoyed it.
While it then took another 10 yrs for me to realy relax and understand my sexuality, I still wonder how my life would have been if I learnt earlier you can still enjoy both.
