I've never been with a shemale/male so I can't say if I would like cum, although I've tasted my own a few times. I tried it for the first time when I cummed in a girls mouth, she kissed me afterwards - (which seems to be something every girl I've been with wants to do). I've recently tasted my own after jerking off after reading another thread, it got me hard'n'horney again.
Every fantasy I have involving shemales though is them cumming in my mouth, and any porn where the shemale cums is HUGE for me - it's the biggest turn on to see a hard cock explode with white goo and go soft while cum drips from the head.
If you have a shemale lover who cums in your coffee every morning, damn you are lucky.
