I've been doing bench press as a woman by myself. It kinda sucks. I've missed a few times and not been able to rack the bar. This has left me helplessly flailing and calling out to whoever is near for help. I hate asking for a spot, but at some point, you just have to. If your gym is crowded, you might be able to work with someone else, take turns spotting each other. There are more women bench pressing than I expected, too.
Female, 5'3", 50, Starting weight: 163lbs. Current weight: 135 (more or less).
I can squat 187.5lbs, press 75lbs and deadlift 200lbs
