if a guy cheets on you and you still sleep with him and have sex with him how can you Know when a guy is having sex withother grils. even thou he acts th e same.

I think if he cums fast he is cheating if he dont c*m fast and its normal its ok but I really dont know I would like to know that question to?

You cant tell if I guy is cheating on you by the way he cums I believe. Well actually it reallyt depends on the guy and how he normally has sex and how fast he cums ect. But its also in the way he acts around you. He may not want sex as much.. oh im sorry this is a hard one. But look for makrs on his body hickies ect dont make it obvious that you are looking for makrs though.

you catch him...

I agree with Danielle. they're how you can tell if your boyfriend is cheating. also if he always calls you by you name and never by "sweetheart" "hun" etc. and then all of a sudden doesnt call you by your name anymore but my sweetheart, hun etc. it may be because he is scared he might call you the wrong name. so good luck...
