Really Self Concious😔

Me and my bf have hooked up before but I'm nervous to let him see me naked... Im pregnant and I'm scared im ugly😔 So I finally wanted to try to sleep naked and he says no... Im really feelin discouraged now... This is me by myself taking a bumpie should i go for it a different time or leave it alone?

Update

So He hasnt seen me naked because im nervous about being completely naked with him... Its not his fault im just not used to the weight ....the babys actual father and i broke up because of death threats and he wished i would misscarry. My current is so lovely to me he knows about what im going through we have been bestfriends for a long time we just started dating and ig maybe he just wants me to wait and to take things Slow for myself... He said im sexy and shouldnt worry about that kind of thing with him. Being nervous and anxious is normal.
