I'm not too sure if you'll be able to help me but I do some desperate advice. I've recently been doing nude modeling for an art class and last night "I came standing to attention" mid way through it's incredibly unprofessional and I'm sure no one signed up for that! I'm really worried it will happen again. Is there any cream or any advice that could keep it down? Please help if you can, im not sure if you answer these types of questions. Thanks
My best advice? Jerk it. If you masturbate before you model for these art classes it might help with unexpected visitors. Stressing about what happened may only make it more likely to happen again, so it's best for you to store your worries away in your very own "well that was funny" memory bank and move forward. Random boners happen, and dwelling on it will only make you more anxious. If you're really worried, whack off a few times before the class to wear your buddy out. Moments like this happen to everyone, so think lightly of it and relax.
Best of luck with future modeling!
