Please tell me I’m not the only one..

I’ve NEVER cared if my SO watches porn, whatever it is what it is and gone about my day. 5 months ago (exactly) I had our beautiful little boy. Again I’ve NEVER been bothered by him watching porn, but the other night I didn’t have my phone near and grabbed his to search something and noticed he had been watching porn. Tried the brush it off but for some reason I can’t, we haven’t had sex like good sex since before our son was born, and sex in general in about a month..I’m breastfeeding and have 0 sex drive and also can’t stand the way I look anymore, boobs are saggy and constantly leaking, extra flabby skin on my belly. I’ve felt horrible that we haven’t had sex in forever to begin with but now I really feel like I haven’t been “good enough” please tell me that I am being ridiculous or at least I’m not the only one who’s been in this position before..
