I think if we was all attempting to break our waters then Id agree wayyyy to dangerous, however its part of ur vagina that most peoples ohs have felt many a times if they've ever done foreplay, especially just before fertile time of the month when its that low! A penis has been sat in sweaty boxers all day, has residue urine on the tip and we don't question shoving that in our foof, but a just washed clean hand we query? But I think to much fiddling probably isn't the wisest of ideas lol xx
