It is different for everyone but in my experience 6 - 8 weeks before I was game enough to attempt DTD.
I had tearing with all 3 and the stitches were very sore and swollen as well as the urethra being very tender.
Also my pelvic joints were tender and stiff as well as my back so mechanically I didn't feel capable of DTD for that reason also.
At 10 weeks we are still taking it very slow and cautious.
You could go for a gentle walk a few days after and there is nothing to prevent you from going out to dinner if you want.
