Would you do a 3D ultrasound...

Would you do a 3D ultrasound at 25 weeks if you didn’t want to find out the gender? I went around 15 weeks and the private facility said they could do another when I was further along and make sure to just make the waste up visible to us. How likely is it that baby will accidentally expose itself? Would you take the chance? I’m dying to see my little baby but don’t want to ruin the surprise!
