First Try Hanging

So I just started hanging the other day for the first time, I’ve only ever done stretching, size genetics and Bathmate before so hanging is all new to me. Using Vac Hanger two things I’ve noticed I get easily excited specially while putting on the contraption but not rock hard, and after I’ve taken off the tape on my glands I’m noticing quite a bit of pre cum, is this ok or will this cause a problem specially as the pre cum is being trapped by the tape for periods of time while hanging?
