FTM over here.

I’m 5 weeks PP and my stitches from my second degree tear are healed. I decided to look down there today and my vagina hole looks so much bigger. How long does it take to shrink back down? I’m eager to swim but obviously won’t for fear of lake water going in (I looked today to see if I felt like I could swim) but now I’m scared that it won’t ever shrink back fully.
