Let's just say "no" :>
What's with all the questions like this? Maybe a girl would like to defend herself :3 I don't see it as gay. >.>
Recently someone asked is it gay for a boy to do yoga! Now asking is it gay for girls to do martial arts ? I'm wondering is it coincidence or troll game! Anyway, let's be wiser to not make these unthinking rules.
Humans can do anything they want, regardless of gender, & there's no activity to count as gay.
Pssh.. Nah
