Or how about this: Peter and MJ with an open relationship? They'd be married to each other, but are consentually non-monogamous, each having their own boyfriends and/or girlfriends and maybe flings (with, of course, every party involved having full knowledge of the entire situation! and some of them also involved with one another - Matt/Johnny anyone?), but of course always using safe sex practices. Orgy with Matt and Johnny and Felicia (and maybe even Ms. Marvel and Harry Osborn? just because)!!! ;P I'll just let anyone reading picture it now. Bwahahahahahaha!!!
