Pedro,
I’m not sure if Oscar was trying to help there, or just wind you up. Sounds like he is very suspicious of his kids. Maybe it’s just that he was a filthy little pervert when he was a kid - always touching himself. I know I was.
Anyway, the bathroom advice is good (if you ignore the whoopee cushion) although your parents will still probably think that you are having a quick fiddle. I once had a particular long trip to the toilet at my grandparents and as I came out I was greeted by my Grandad telling me that he knew what I was doing in there. “I was having a big shit grandad” I wanted to say (and was the truth), but was a bit taken back by my grandad talking about me playing with myself.
Try running the shower while jelqing, you can jelq in or out of the shower, but make sure that you get yourself wet before coming out of the bathroom. You don’t want them to hear you in the shower for half an hour and then come out bone dry.
Other ideas are things like hanging your coat on the back of the door, so that whenever you are PEing it *accidentally* falls onto the floor stopping the door from being opened for the few seconds you need to pull your underwear up. Alternatively, you can jelq in bed at night or in the morning, no one can blame you if they walk in and you have morning wood.
Otherwise tell your dad you need some privacy, or if possible get a lock on your door. Your parents will think it is more filthy behaviour, but they are going to think that you are doing it regardless.
Well, I hope that makes some sense. As for your routine, it is fine for starters. Eventually, you will want to build up your routine, but hopefully by then you will have worked out a way to get more privacy.
Good luck.
