Looking to get into MMA or boxing

Hello, so I've recently sparked the interest into getting into boxing or MMA (emphasis on Muay Thai and jujitsu no-gi) and I wanted to ask if there are any others out there curretly doing either or both? I don't really know much except that its quite hard to find a place that seems to welcome females around me and that there doesn't seem to be much information I can find out there about jumping into it. I'm in my 20s and would like to do this not only for fitness but if I like it I'd be more than willing to compete. I'm a bit intimidated jumping into a gym with all guys but seeing as the boxing/MMA world seem to be dominated by men I'm guessing I'll have get over that. Any tips? Anyone out there currently doing this?
