i would usually agree, but i once had a 4 hours or longer sex session with and amazing and rele beautiful girl 9,5/10 maybe even 9/8 and i say that because to me true perfection doest exist and well my point being that those 4 hours of sex were amazing!!! not one second it was boring or anything but the next day my dick kinda hurt... still worth it! but i guess thats something u can't do very often
