is it for you sweetheart or him? cause if you are curious about trying out pegging him which by the way is incredibly hot ๐ฅ, cause there's strap-ons that can actually squirt and believe me he'd love to feel you shooting in his behind, but if it's for him to increase size or girth, then I'd recommend first measure him both ways length and girth, cause it can be extremely uncomfortable if it's to tight or loose, love to chat with you more seriously I'm a newbie here as well
