I think it's a kindergarten-level question. You have not yet realized that a girl or woman cannot be “yours”. Fighting over NTR always makes me laugh. Perfect logic: 3-some/harem ending = good. NTR = bad. LOL wtf??!
Toys - if a woman likes it, why not.
I'm not offended by it by any means but I'm not that turned on by toy-scenes so I tend to skip over those a lot of the time. Definitely don't mind if they're brought up in conversation or whatever though.
