Help with ケ in this sentence/phrase?

Question

I'm still learning japanese, so I'd like someone to help me with this, please!

I can't understand the meaning of this phrase/expression:

そっちのケはないんじゃ

I do understand the meaning of はないんじゃ, but I don't know what does "そっちのケ" means. Thanks in advance!

Answer 1

「そっちのケ」, or 「そのケ」, 「その[気]{け}」, is a euphemism for "interest in the same gender", "homosexuality".

E.g.
そっちのケがある → have an interest in the same gender
そっちのケはない → have no interest in the same gender

_{The ケ comes from...}

_{け【気】
🈪〘接尾〙《名詞、動詞の連用形、形容詞・形容動詞の語幹などに付いて》そのような様子・気配が感じられる意を表す。「[人気]{ひとけ}・毒気（どくけ/どっけ）・[食]{く}い[気]{け}・[寒気]{さむけ}」「[嫌気]{いやけ}がさす」▷「しゃれっけ」「商売っけ」のように促音「っ」がはいることもある。
