Is sexting with another person cheating? so i met this guy and we just talked openly about several subjects (i do not know him really well nor know him in person) we got a little personal got ideas and we ended up sexting i already have a boyfriend he is really sweet we been together for 2 years in which i wanted to try several things but i didnt talk to him about making our realionship open and yeah things but fter sexting i didnt agree nor did we talk about an official relationship(or just any relationship) with the guy i had sexting and he has his own girlfriend from what i know it feels like cheating and i feel guilt for agreeing to do it and apart from that theres a huge age gap of 6 years.
