I'm 5'3 and 150. The first time I was with my then-summer fling/now-husband was the first time I was ever fully naked, in full light, with a man. (Although not a virgin.) I was nervous, but also very comfortable with him. I could tell this wasn't just any fling, it was something real. And if he didn't accept me, then that would be a sign I was wrong, it wasn't real. I certainly was not interested in some ass who'd make fun of my body. We've been happily married about 10 years, so obviously that first night, and many, many after, went pretty spectacular.

My marriage is monogamish, so I've had sex with a dozen, give or take, other men over the past decade.

And, yes, I have had a couple guys say hurtful comments about my body. Not my size (even though they've all been fitter than me.) They might say something about my "fat ass," but that's always a compliment. I scar easily, and my breast are scared, they are not my best asset, and a couple guys have pointed it out and it's made me self conscious. Yes, it hurt. But ultimately I know they've said it because there was something wrong about them, not me. (Soon became clear in both cases they had some issues.) What did I do? Stopped having sex with them, picked up my pride, and moved on. Life goes on.

I'm going to assume, being together for over a year now and considering sex, you and your boyfriend love each other. You probably notice a thing or two about him that isn't perfect, but you don't care, you love him. Unless your boyfriend is blind, scratch that, even if he is blind, he knows your size by now--and doesn't care.

And seriously, 5'7 and 150, and I know you're insecure, I get it, but I bet you have an awesome body. Curves are hot. Have you made out in just a bra and, say, yoga pants? Practice that. You'll get comfortable.
