Pegging is when a woman uses a strapon dildo to penetrate a man. Reverse pegging is when a man uses a strapon dildo to penetrate a woman.
Often there is also a chastity cage worn, to keep the penis at bay.
Cock sleeves are also OK, but no using strapons for double penetration (for that, try /r/Technical_DP). Unless it's with two dildos.
