As a cis male I can say that feeling guilt after mastrubation is a very common thing. I suffered from it and I know several friends who did as well. Some even having strong feelings of depression after.
It might not be related to coming out because it's a normal thing for males as well. For me it went away with age. A friend of mine unfortunately still suffers from it (even after sex).
It might be useful to talk about this with a psychologist or by trying to be more accepting of your body in it's current state. I'm not saying this is easy because it took several years for me to overcome some psychological problems but the hard work paid off in the end. It's something that requires an active effort every day.
I wish you the best of luck!
Hey hey, check your facts, the Shield did get an update recently. They did in fact add ads to the home screen./s But I assume you mean a hardware upgrade.
But on a serious note I don't see a reason why I need anything else than the Shield. It has flaws and bugs but generally plays everything. Combined with my Plex home server the experience is great. Can take the shield anywhere I go and stream content from my home server.
I play everything in 4k blueray remux without any problems (except for a memory leak every few weeks).
