I actually did both, peeking and not peeking. It was actually handled quite well in that all you got was a look at male genitalia like so many games have done with the difference being this is a male choosing to look at another male. My second playthrough I used the patch and walkthrough and chose to not peek because I also am not into that genre. My plan is to play this as a friendship rather than a sexual relationship.Not really into traps but Nea is fucking adorable. I didn't peak because not really into feminine penis lol
Edit: In short @Luxee handled it quite well and wasn't over the top.
