@Cynthia777 to be honest, if you had asked me at the beginning ie from day 2 to 9, I was asking myself the same question. Why did I do it!!? I mean I actually requested to have both done!
But...
What I have learnt from this forum and reading loads of stories, is managing pain relief. I did not realise until too late how important this is along with rest, icing and not doing too much, oh and using crutches or canes.
So the issues I had were not being mentally prepared for the muscle and groin pain I had, in what was, before the op, my best right leg, AND pain control in the hospital and the next 9 days at home, which just wasn't controlled.
Now the left leg; which also had a torn labrum like you (?);was extremely painful and stiff before op. This leg however had less pain post op. Today I have little pain in it at all 3 weeks out, except a very very slight throb.
The right leg, however, still has the muscle and bone ache lurking, but again, it is down to me making adjustments in pain relief meds. I also keep walking about too much and not resting up. I am also naughty as I think..ooh less pain I will walk about with no sticks and then I pay for it later by limping and hurting.
I am now doing as I am told

.
So to answer your question on day 21... Yes. I am glad I have had both done together, as it means I dont have to go through the same recovery period for a second time in august/September. Which would mean another period of time healing, inactivity and possible boredom setting in!!
So, although you may or may not get lots of pain , shown by my hips reacting differently to the surgery. Be pain aware before surgery and get ready to demand where necessary the correct drugs to see you through the initial period. Dont over do it and use sticks etc.
Know there is light at the end of the tunnel and be positive.
@Michegon and
@djklaugh both had bilateral ops too. So hopefully they can give you their thoughts to help you decide if you are asked by the surgeon.
