Started experiementing around 12/13 and had various experiences before I was 100% sure that doing gay stuff in the closet was a turn on. I had one friends older brother who wanted to mess around and he was def very manly. His cock and moaning when he was shooting sounded exactly like yours. First couple months I would cum no matter how hard i would hold back just hearing him moaning and telling me he was gonna cum. He did stuff diff than most of the the other guys. Sometimes flesh light or vibrator but would pull out before and shoot on it towards me. He was a virgin until his mid 20s prob because he liked finding blowjobs from guys. He def liked how horny gay or bisexual guys would let him do whatever he wanted because of his thick hairy dick.
