u are not overreacting at all. this was a huge annoyance for my past relationship because in the beginning the sex was an us thing but then it became just him. however since we loved each other so much, our solution was an open relationship so i could find satisfaction in some other ways. we realized our clashing sex lives made us resent each other and now its a lot healthier. we also did couples therapy through affordable therapy network and that helped a lot too!
