So if you want hetero smut you should try josei manga. Also when you're choosing your genres you can sort out those you dont want. So u can just put an x for all non straight tags and then look for smut :)
yeah here's the list of titles tagged with smut without the yaoi and yuri tag

https://www.mangago.zone/genre/Smut/?f=1&o=1&e=Yaoi,Shounen%20Ai,Yuri,Shoujo%20Ai here i did it for you. Im not sure if you can find mixed manga the same way but you could try tags like 'bisexual' or look for josei and yaoi/yuri at the same time
oh thank you :)) i didnt even consider this
tysm :)
anyone have some good smut (not just ecchi) thats hetero or a mix of yuri/hetero, yaoi/hetero or both? theres a yuri and yaoi tag but none for straight stuff so im struggling. Also dont rec the ones with insanely weird bodily proportions to uplift the male reader please.
