I’m sorry, I found your post quite hilarious and it took me a while to stop laughing and actually type up a reply.
There are no other scenes of that nature in Fate/stay Night. On the other hand, a very large portion of other eroge ARE going to be dangerous for you because this sort of thing is extremely common and a lot more common than yuri. It’s also so common that generally eroge rating sites like EGS and vndb will not bother mentioning it (well, vndb might have a tag for it but it’s not going to be used on anywhere near the majority of games that have it), so it’s going to surprise you every time I’m afraid. I actually feel for you in this regard - it’s sort of like how I hate paizuri scenes (well, I generally just skip them if they appear, but nonetheless- I like naizuri though) even though practically nobody else seems to.
