Because I feel OP wants an honest answer I will give one.
It's not much different than being a man I would guess. Someone mentioned breasts getting in the way, but honestly I barely notice them. Think of it as having a limb you just forget about. The only time I notice my own is if I drink too much caffeine and gives me this issue with mastalgia. It's incredibly painful and about the only time I notice. You never really realize how much stuff you lean up against until your chest feels like it's on fire.
Other than that, I never really think about my gender. There are things I notice, like when people are being a dick to me because of my gender, or the fact that I prefer characters that are my gender to reflect myself. But really that's about it and I really don't think I'd ever want to be a man cause I'm pretty comfortable as is.
