Randolph C. Harrison's ass, 261/2 years
One of the advantages of starring in an explicit gay drama is the sheer amount of skin you're forced to expose on a regular basis. Some might view this as demeaning or simple titilation. To this I say:
BULLSHIT.
You are working with a heretofore 'straight' man. Short of molesting him, you *want* him to be well aware of you as a sexual being, to notice when you're naked, and focus on whatever your best feature is when you're naked. Of course, if all of your features are equally attractive - as in my case - you have a lot more to bring attention to, which can only work to your advantage.
Here, for example, is a picture of my ass:
Something this well-formed and sag-free you want to bring attention to. Therefore, follow these simple rules:
1. Shake your ass in his face at every opportunity.
2. Comment on your ass in some way that will draw attention to it without sounding negative, i.e., avoid "Does my ass look big in this?" and go with "My ass looks hot in this, right?" instead.
3. Get someone else to comment on how great your ass looks when your Straight Co-Star is nearby (gay friends are an excellent choice for this one).
The best opportunity when being naked with him, however, is the simulated sex scenes. In general, the process is very clinical and professional - the set is emptied of unessential crew and the director is telling you to thrust a little harder or moan a little louder, and it makes the entire process devoid of sexuality.
Still, a long-time thespian such as myself can find moments in every sex scene. When the camera is not rolling, make sure you keep in physical contact with your Straight Co-Star at all times. Even if it's something as simple as rubbing your hand on their forearm, just keep reminding him that you are always there, and always naked.
Of course, don't take it too far or you'll find yourself slapped with a sexual harassment suit and be forced to hire a lawyer at $400 gazillion an hour.
