I disagree. I'm a straight/curious guy and I agree that women do have asses on them, idk what girls the others have been looking at, but i know plenty of girls with big asses, bigger than most if not all guys ive seen.
But anyway..i dont think that womens asses are disgusting. im a huge ass fan but i love an ass on both men and women, but lately an ass on a guy has caught on to me. And anyone who is attracted to guys would say that "mens asses are hotter than womens"...i mean, thats a bias statement.
I dont know what straight guys you have been talking to but i dont know ANYONE that resort to female tits to fill their nostalgia for male ass. You cant just make a statement like that lol, everyone has their own fetish. Not ever guy has to resort to tits, i know numerous of guys/my friends that love female asses for jusst as they are and female tits for just as they are. Me personally, i love female ass AND tits and i don't resort them to fill needs for male asses. But also, i am a huge ass fan, so i love asses on females and the male has has grown onto me, i wont lie haha.
But yeah, idk where you get your info from but that is not entirely true, or true at all.
PS. i am not speaking for ALL straight guys in the world, just myself and the ones i know.
