Men: what was your first bisexual experience?

I don’t really count an early teen experience. I had no idea about sex then but it did plant a seed.
Later in life, l was watching lesbian porn for arousal. I came across a gay vid and got an instant erection. This lead to alot of masturbation looking at naked men and gay porn. This eventually made me want to try the real thing. I’m so glad I overcame my nerves and met a local man. It was a brief meeting but afterwards l felt so good about myself.
