is it just me or almost every seme doesnt like sweets xd

exactly... it’s usually all the ukes...

I know, right? The only one I know that isn't like that is the ship Shizaya from Durarara. :/

Here, both the uke and the seme have sweet tooth

Seme’s have no taste. :,) Only uke’s get taste buds on their tongues.
