This is a question you should ask your doctor. Your doctor knows the extent of the surgery done, and how long you should wait.
I couldn't find anything specific to an orciopexy, but generally speaking, doing too much too soon, could strain the incision line or stitches, if they haven't dissolved yet, or it could just hurt.
Give your doctor a call or wait until your follow up appointment and ask then. And don't be afraid to ask - your doctor masturbates, too.
