If you get red, yellow, green, or magenta spots on the glans of your penis then chances are that it is temporary inflammation of the blood vessels. If it doesn’t hurt then you should be okay. If you were doing jelqs, which I assume is what you meant by newb routine then those should go away. The only thing I can think of is to take it easy at first.
Jelqing is a rude awakening to a couch potato penis. You don’t run a 10k marathon you first day out of the house. Remember you tell your wife that you are going for a run, catch the bus down to the bar and before you leave you splash some water from the bathroom on your face. Eventually you get really athletic and walk down to the bar. Heck you may even break a real sweat. Same thing with PE.
So as long as you don’t feel pain and listen to your body you will be fine. We all go at different speeds so don’t be reckless or try to compare yourself to anyone else. Some people hang 20 lbs off their dicks the first time they hang, some do jelqs for 40 minutes in their first week. Even after a year of jelqing I could never get past 30. Just do what feels right and don’t ever do anything that feels wrong.
