You want the meme rubber from japan. .001 thin as can be. Okamoto and sagami are my go to brands. Anal has to be raw, well prepped and clean. You get a strong clamping pair of muscles that will milk you in minutes, or go beyond and it'll hold you in place while you get softer stimulation that can go forever. Assholes can be so tight as to squeeze you boner soft, comes back in half a sec if you don't panic tho.
Tbh sex is as awesome or lame as everyone involved. Can suck, can be bliss.
