Does the word iroppoi refer to male/female or both?

Question

I would also like to know how to say in Japanese (hiragana or romaji) "you give me butterflies in my stomach" (yes i am trying to hit on a cute Japanese guy!)

Thanks!

Answer 1

Iroppoi is only for women. Guys would be kakoii, shibui or steaki but never irropoi or pitchi pitchi. You can also use kabuki lingo to describe men such as tateyaku for strong and silent types like Ken Takakura, or nimaeme for sensitive types like Takuya Kimura.  

Answer 2

>Does the word iroppoi refer to male/female or both?

It's female in most cases.

>you give me butterflies in my stomach"
