Shy during sex

I’ve gained weight. I can just see it.. I’ve struggle ever since having my daughter.

Now I’m so insecure during sex and I know that can be such a turn off for men.

Is this normal to feel that way?

I’m 5’1 163lbs

I haven’t gained any weight on the scale but I’m noticing changes in my belly and everything and it’s so embarrassing

I drink a lot of water and going to start running this week to see if it helps.

But I just want to know I’m not alone. Here is my fit handsome boyfriend and I feel like a whale 😩

Picture to show body type. Definitely doesn’t show everything but my tummy is definitely struggling
