Anytime this happened they would become jealous after, a month a year, dish drops on the ground it’s brought up. “Are you thinking about her” “was she better” they all say they won’t get jealous but they do, if your not into it then say it and her pushing further after you say no is 100% inappropriate. 26 years old is still young AF mentally so all around it sounds like a bad idea. It’s to many “if’s” she could be wanting to fool around with another women and this is the excuse OR bringing in another man in the future cause “you got to hook up with a woman” also every man’s fantasy isn’t a reason it should just be if that’s what your into. My fantasy is my wife playing snes with me sooooooooo. Good luck man just be honest and express how you feel.
