I was married at 20...I had been curious and even spent a weekend with a guy I knew was gay in a fishing lodge just before the wedding. During the second night he got into bed with me...I was nude and so was he. I woke up and told him I was ok with him being in my bed but that was as far as it could go. We just talked and lay close. I got an erection and when he fell asleep I masturbated and ejaculated. He didn't know that.
When I was 28 I ran into I guy I sort of knew at a conference. I hade met him previously briefly and had seen him nude in a gym shower. After seeing him nude that first time and getting an erection I went and masturbated in the locker room toilets.
When I met him the second time I felt real urges. He invited me for a drink after the final session for the day and asked directly if I was still married...which I was.
He said he had seen my erection in the showers and it had really turned him on. I said I was married and str8, and said I had been embarrassed getting an erection that time. He just laughed and said it was perfectly normal for guys to get aroused with other nude guys around. But then he added it was a pity I had wasted load when he would have happily taken it down his throat. I was pretty shocked with the openness but it made me really horny. So, when he suggested we had dinner I was happy to go along with him, wanting to spend more time. We sat down at dinner and a booth and ordered a cocktail and then I just blurted out that I wanted to go to bed with him...he was quite stunned but quickly recovered and put his hand on my bulging crotch. I nearly ejaculated. We quickly finished our cocktails and went to my room were we spent a night of intense sex...my first with a man. He was very gentle and guided me through all the experiences of my initiation. we had another night together and I left that conference knowing that gay sex was always going to be a part of my life. It has been ever since. I am still married to a woman I love and enjoy being with, but when I travel which is a lot, I indulge with men. It just works for me.
