I think that if you have the confidence for it and your guy would enjoy them, go for it! B-pics are all about being sexy and feeling sexy, and to be honest your guy is with you because he loves ALL of you, including your body. I'm
very insecure about my plus-sized body, and wearing sexy lingerie was a huge step for me, but I know that DH finds me beautiful, and I'm feeling a little more comfortable.
I would say if you want some inspiration, look at some of the old-time pin-up girls. These ladies were curvy, and they had some really cute outfits, but you can also go for some beautiful nightgowns as well. Then find a photographer
that you can trust; if they've done b-pics before, they probably have ways to make ladies feel comfortable with the process.
So if you want to do them and you think your FH would like something like that, I'd say go for it!
