Feeling insecure

So I'm 11 weeks with my second and feeling huge, gross and very insecure. My sex drive is still in full force but I'm still 100% down to do the deed but it feels like my SO is more excited to rub one out which would be fine but here I am more than willing and he knows this. Its making me feel really low and incredibly unattractive. We've talked about a little but he is still doing it, am I wrong to be upset? Ugh feeling like I'm to ugly to be touched
