So there is this girl that has a great body and an okay face, She has a boyfriend of 2 years and she wants to have sex with me. She uses dip and has disgusting teeth though and she is just really really poor. But I am sure the sex will be good. How do I stop myself from doing this? I fear too many things will go wrong like she will try and get a kid out of it or something. Or ill get shot from the hillbilly boyfriend. She is a cheating whore obviously but im horny and lonely
Find a girl that's really good, physically, mentally and emotionally. Make it your goal to get that girl and be happy. You'll better your self physically, mentally, financially and emotionally, in trying to attract the good girl. You'll forget about the bad one completely, however tell her right now straight up you don't want to do anything. If she accuses you of being gay, or being a ass hole or some shit, get her and others like her out of your life, scum will accumulate in your life and ruin you (or you can just ignore her harsh comments and stay strong).
However getting in a relationship with someone you really like isn't necessary, it's just a common tactic to keep someone focused in life and feel happy. You can do whatever you want, in life, it's your job to find what you want and get it.
Good Luck OP.
