I know it's a slightly contentious subject on here, but something I enjoy, so if we could skip past the "but why? How could anyone enjoy that?" posts...
As I say, I enjoy fisting, vaginal only. We have tried it quite a few times, only enjoyment and pleasant pain, not proper pain. Today was maybe a bit rougher than before, slightly painful during the act, but still mainly enjoyable. For the past few hours though, I've had an unpleasant aching, not vaginal, more like afterbirth pains if anything. No bleeding and nothing that would hugely concern me, but could anyone who's tried this more than a few times tell me if this is something to be concerned about, or simply a hazard of the activity and to forget about it?
