Dear Jackie948,
Are you open to something like attending yoga classes? When I used to go, the classes had 10-25 girls and only 0-3 boys. I would go to the same classes every week so usually the same people were always there and you start becoming friends. Avoid the M-F classes scheduled between 8:00 AM and 3:00 AM--those are typically classes that Mom's go to after taking their kids to school but the rest of the time, most of the girls were close to your age. You might be able to find one that fits your schedule.
Also, you are in a career field (IT) where there might be "networking organizations". (Most larger cities have them) While you are in an industry that has more men than women, women go to these meetings, too. Though I know your schedule might make this problematic.
Just some ideas.
