They were wearing their costumes, which are presumably armored/protective. Oh, is that not what you mean by safe sex?

I think the Batgirl thing is tough (and I say that as someone very disappointed about no longer having a decent BoP and no Oracle, who I thought was unique in comics). I can certainly see why advocates for a change ask why she's the one character who DOESN'T get better. Others come back from broken backs and death, but Babs was always in the wheelchair. I think you're almost forced to ask if it's because she's a woman ... but at the same time Oracle is all kinds of awesome in a way that just being a bat-knockoff doesn't make me have any real interest in reading even if it is Gail.
