Yes there certainly is. I let an ex gf vibe my prostate once then she fucked me with a strapon untill we both came . I fell in love with it right then and there as my hips shook and my cock squirted large amounts of cum I begged her to keep fucking my ass. She knew she had me. I was turned out her lil cock whore. To this day I can't achieve orgasm unless I have something in my ass
