Just started learning and wondered if you could help me?

I'm looking at personal pronouns and wonder which of the following are correct (both might be wrong).

Ben sıcakum or Ben sıcakım - Meaning I'm hot?

Thanks

As grammar, second one is right, but fs a suffix come with a vowel to a word ending with p, ç, t, k they are changed as b, c, d, g or ğ
so;
"Ben sıcağım."

but meaning isnt clear .We dont often say a sentence like ben sıcağım .

Do you wanna mean "It's hot so I am feeling bored?

If you so,you say;
Sıcaklandım as an ideom.

maybe yanıyorum

Maybe you want to say something like you are sexy? As far as I know, sıcak is not for that

Maybe ateşli?
