Quick Question

Hey I'm newly 18 year old, gay, in Sydney Australia and am going out to a gay club this weekend. I have no gay guy friends, so I've opted to take a few of my girlfriends (all straight) out with me.My question is, would that be weird or looked down on ? Like is it normal to take your straight girl friends out with you, or should i wait till i have some gay friends to take with me? I only ask because i don't know if people prefer the crowd to be all Guys or...?I don't know if this is a stupid question or not, i was just thinking it over in my head the past couple hours. Thank you!!!
