I like watching/being watched, whether just jacking off or fucking/getting fucked.
I also love having a guy (or two) cum on my chest
I was at the bath house one night in the porn room with 4 other guys. The guy closest to me asked if he could cum on my chest and I said "yes!". He stood up and stroked his cock a couple times, then proceeded to drench my chest with his load. The other guys definitely enjoyed the show and I walked to the showers with his cum dripping down my chest
