Killed the mood

My husband and I have been sexually exploring each other and I let my insecurities screw up our vibe. He always talks about a 3 some bc he wants to watch me with another woman bc I’m sensual blah blah, etc. he always wants to know what type of woman turns me on etc. he texted me earlier going on and on about this amazingly sexy 3some video. So, I asked to see it and he gladly showed me bc I was genuinely interested. Well, it’s 3 gorgeous cookie cutter blondes. Big boobs not an ounce of fat. They had beautiful long hair, wearing body jewels etc, they were tan. And his dick was hard as he showed me. I immediately felt undesired, gross, insecure, shy, modest, etc. I’m 3 weeks post partum with 2nd child and I’m plus size, stretch marks from pregnancy, pale, dark hair... literally the opposite of those women. I told my husband to stop the video and just said it wasn’t turning me on. I prefer he just talk dirty but watching porn with him made me very self conscience. He felt like shit and several times said it’s not the women it was the positions and he was imagining me between them and he thought I was turned on bc we talk about it during sex. I explained it’s just me and I’m not happy with my body and it’s hard to watch your husband get hard over women that look nothing like you. The convo ended awkwardly and idk what else to say to him. I hate feeling insecure. He said he hates his body too (he’s a big guy) but I told him I can’t help it.
