i have mine doneee honestly the best thing i have done for myself.
im 21 and got mine done a year ago in last may.
the only down side is the recovery period, other wise i dont see any other possible down sides.
i am really happy with mine! and my DP lurrrves them during play time haha
i guess you could say they make you feel alot more confident.
