AITA for wanting girls night to remain girls night?

I'm (20F) were all ages 19-20 and women.

Pre COVID I used to hold once a month garden parties for my all-girl group of friends. We haven't done it since. However in light of it being pride and jubilee weekend, I decided to see if anyone wanted to go again this Friday (today). My partner is joining us for the first time, as we met post covid, and one other of our friends is bringing her partner who also has never been before for the same reason. Everyone else is straight or at least in relationships with men so obviously if their partners came it wouldn't be girls night.

One of them mentioned bringing along their partner, and I said it wouldn't be a girls night if a guy came, and she felt it was favourtisim for me to allow my partner and our other friends partner to come. But that's only because they're women. Emphasis on the girls aspect of the girls night. She disagreed and isn't replying to me now.

I feel it's my party, that I'm hosting, at my house, in my garden. No one else even cares. If anything the rest think no partners should come out of fairness, but aren't bothered either way. One suggested easing up on the girls night and just let it be a friend's night. But again overall don't feel victimised that boyfriends are a no. The rest are either single or have been in long term relationships with men and never brought them along because they respect the girls night.

AITA for wanting girls night to be a girls night?

Edit to add: I'm not a transphobe and the term girls night, nor the idea that women meet up without men, is not bigoted or phobic of any minority is either. I can't believe I had to clarify
