It's also important to communicate with MuscleVIP. I've never hired him, but hopefully he would be responsive. As mentioned before, you would want to relax and loosen up. You can do this by building up during foreplay (e.g., fingers, dildo). Remember, porn is a fantasy. You're not going to be able to go from 0 to passionate thrusting. Stop/slow down when it hurts. Use plenty of lube. Many guys who are well endowed understand these things, but you still need to communicate.
