I'm thinking of raping my girlfriend so she doesn't get with any other guys.
Thats horrible. How could you even think about raping your girlfriend?
I want to be the only one to have her.
It is wrong to rape someone and a very serious crime. You should get mental help for your thoughts.
But she is so fuckable.
Sexually abusing your girlfriend to keep her from cheating on you is horrible. Your relationship would be ruined and you could be charged with a crime. It's going to be really hard to stay in a relationship with her when you're in jail for sexual assault.
