worries and questions?

pp, ignore the stray hair

I(36M) am in my 5th week of just stretching and not sure of anything. I can only pull the tip when flaccid, but 30% was like too much when I started, and erections would only show like 15%; I thought that was normal. I have been tracking my progress with videos when pulling, just for me to see. I didn't expect to ever share them, but I found this sub for information and noticed the color in my skin is kinda weird(? The video shows the first time I ever pulled it behind the tip that much(yesterday), but it looks pale and kinda weirder than other videos I have seen here. Is that something to worry about?

I can't pull it without lubrication. I normally just put a little coconut oil in the foreskin to start, and my body generates the rest. Should I be able to pull it while dry? I am not sure if I can't, but I am sure it wouldn't feel right or fear for irritation, irritated pp is not nice. Sometimes I have felt a slight irritation, when that happens I just stop stretching for a few days. Is stopping what is expected or is important to stretch daily?

Lastly, how probable is paraphimosis? I spend more of the time with fear of causing a medical emergency, I concentrate a lot to be flaccid because I fear erection may be dangerous. I don't test it daily, but like every 3-4 days of stretching with my fingers.

Thank you for your time.
