Wdy Think? (TMI)

Okay, so this is kind of personal but I need someones opinion.. me and my boyfriend were having sex last night and he wanted to do it doggy style. Well I'm not very comfortable with it because I've had a child so air easily goes in and out very easily if you catch my drift. I obviously tried it for him, the inevitable happened and he said he didnt care and then tried to go back in but like the angle was wrong so he got frustrated and yelled at me because I didnt want the light on...

Like I already was feeling self conscious and then he yells at me. And then when I start crying he doesnt comfort me because hes upset?? Like wtf. Am i over reacting orrr???

I'm 15 weeks pregnant with his kid and he has been super snappy with me lately. Even screamed at me in front of my two year old a few days ago...

(EDIT) he got mad because he couldnt get it back in and blamed me for not wanting the lights on as to why he couldnt get it back in. When it was because of the angle, not the lights.
