There is nothing better than jacking off and watching a woman jill herself at the same time. I have as much fun doing that as I do having other forms of male-female sex.
At the same time, I've jacked off with guys too and I enjoy that as well. For me that is more recreational. It feels good so lets do it. I've also jacked off other guys and I've been jacked off by other guys. For me anyway, it isn't that I've gone gay and want to kiss them and stuff like that, it is more of just a fun 'other' way to get that wonderful orgasm we all love. Many of us guys are kind of proud of our hard dicks and we don't mind showing each other. After that things just happen naturally.
When I was a teen, I had a friend who I jacked off with a couple of days a week after school. His parents were both working and we had his house alone. We would jack off together and see who shot their loads the greatest distance and stuff like that. We also had contests to see who could cum the quickest.
As an adult, I've jacked off with at least a dozen guys. With at least six of them we jacked each other off and it felt great.
If I had a choice, I'd be with a women every time but the guy/guy thing can be fun too. No harm done.
