The reason she's pointing out other guys is to see how you react. If you say nothing, then she reads it as you giving her consent that it's ok. If you get angry or defensive, she will read that as a weakness on your part. If you engage in the conversation normally, she will also take it as both weakness and permission. She's doing this because she is either already with another man, or setting the stage to make a move with another man. She's setting this psychological framework where she's finding ways to 'give herself permission'.  It may also be another woman, you never know - she might also be trying to show how she likes men to set a smokescreen. Don't be surprised if she soons starts pointing out women for you, or telling you it's ok if you find other women attractive.. again, looking for points of reference to refer back to to say, "Well, he seemed ok with it, and I said it's ok if he did it too". She's kind of creating a fantasy of an open relationship without actually consulting you on it.

There's nothing wrong with you, or your penis, or anything. You're with a manipulator. She's playing you. Don't play the game.

in regards to the sex, you may just be boring in bed, that doesnt excuse bad behavior but the truth could hurt. 

If you suspect your Partner is cheating or doing something you aren't in support of, there's a way you can now know what he's up to, an old friend gave me the contact of a man that helped me nab my cheating ex-boyfriend and saved me from a terrible relationship, If you're a student with bad grades too, you should probably contact him.. his services are straight and forward and trust me, he gets things done; elkhanov9@ gmail. com. Thank me later.

Yeah, she's cheating. When she comes home, hold her down and take control, fuck her hard one last time, then leave her. She is fucking other giys and probably looking for someone who is better than you for her to leave you for. Women like to 'cheat up' essentially cheating to find someone better than their significant other.
