try something from this list maybe? https://www.mangago.me/tag/Rape+%E2%9B%94/?page=1
EVERYTHING can affect your mental health, but a lot also depends on how mentally and emotionally strong you are and how you cope with it (I have to say, intelligence also matters here), and reading a genre where these elements are present doesn't make you a bad nor dumb person. Just like in horror, someone getting killed is a bad thing, yet you don't become a murderer or a bad person just because you enjoy the genre. (There are always exceptions, as some people are unfortunately capable of changing and replicating these things because of it.) Showing an obsessive amount of interest beyond a certain point can be a sign, but just because you're mentally strong enough to 'enjoy' a story with elements like these, it doesn't make you a sick person. If you watch a movie what makes people sad and cry, nobody gonna assume you like pain and being sad. Every genre has their reason why are those exist, adrenaline, sadness, shock, etc.
No obviously. I'm not saying one becomes a rapist if they indulge in media that includes rape, so I don't know why you mentioned "you don't become a murderer" part. I'm saying it's weird, it can still affect your mental health because it IS one of the many things that affects your mental health. Especially if you consume a lot of it, as OP is obviously doing. It's weird, it makes them a weird person because why are you actively enjoying reading someone getting raped and then asking for more of it like you're asking for seconds.

Recommend me Yuri and yaoi mangas with rape
