Is it normal that i'm afraid for a guy to see me naked?

Me and this guy have this really strong lust connection, I never thought it was possible but it's like the lust you see in movies he just wires me up in a way no one has before not even my ex boyfriend of three years, and we agreed to have no strings sex but I didn't go out of my way to see him for it or anything. At a party we ended up having sex and it was great. Even though it was all fun and what not he even made it more sort of special than my ex ever did like he spooned me and kissed my shoulders and stuff.

Now, almost EIGHT MONTHS later he still keeps talking to me saying he wants me to come to his house and have sex again coz it was so good.

This guy is lustful perfect like everything I imagined I'd lust for and a gorgeous body!!!! OH MY GOSH. which is where my problem is... I'm VERY self conscious about my body most of my is fine it's just my stomach I feel it's not normal compared to others and I think it's fat - like sincerely not being all silly about it, most people say I'm not but I think my clothes hide it really well

I want to see him and sleep with him again - especially after I said what if I've grown a monobrow and gained 50kilos?? and he replied with you'd still be funny and great in bed and I'd still look at you. But I just can't pluck up the confidence I had back then to just go see him and do it.

Opinions?
