I got called insecure for not wanting to fuck a sex doll.

I (F23) was hanging out with my boyfriend (M24) at his place and we were browsing a shopping app on his phone. Everytime I click something, an ad for a sex doll would pop up and it was weird. He was joking that maybe the ad is for him but I took it as a joke and laughed along with him. <br><br>Later that night, he brought up the topic of the sex doll and said he wanted to buy one. I asked him if he was serious and he said yes. I told him I wasn't okay with a sex doll in the house and he said I was too insecure. I told him that I wasn't okay with him having sex with a doll because it's cheating. He said that a doll can't be considered as cheating. <br><br>We had a huge argument over this and he said I was overreacting and I don't trust him. After a while, he agreed to delete the ads and promised me he wasn't gonna buy the doll. Was I overreacting? I mean how would he feel if I got a sex doll? And omg I can't imagine the doll in the house, it sends shivers down my spine.
