I've been cheated on before and I used to get mad when it would happen but over the years I've realized, there's no reason to get mad. Ever since I saw my highschool gf (at the time), literally sucking my friends cock, I just realized how hot and normal it is. All the time you hear people getting divorced and changing their lives over it, but why, its just sex and it's making their S/O happy. Now years later I've had more relationships and none have ended over jealousy or cheating.  It's actually a relief not worrying, hell it's brought my current gf and I closer together.
