Is there sexy underwear made for men of size?!

Hey guys. I'm 26, 5'11" and 340 lbs. partnered for 5 years looking to spice things up. Is there underwear designed to enhance the package of a big man like myself? Maybe something really tight over the fat pad and with a cock ring to sort of bring everything to attention? I want something open so I could wear it during sex. Is there a website with a good selection of sexy lingerie for big beautiful gay men like myself? Help!
