I've been recently considering the idea of pegging my partner (we're in a D/s relationship and I intend to penetrate him anally as a form of punishment), and I've been flirting with dildos and anal plugs made of glass for several weeks now, since they require very little lub to slip in easily and serve well for temperature play.

I fell in love with Icicles No. 2 (love that it functions somewhat like a bead stick), but we're both beginners, and I've heard of people getting it stuck inside since it lacks a base. So I'm wondering if I should get the glass probe instead? Is Icicles No. 2 safe for anal use? Would you guys and gals recommend me something else? My partner is FTM, so no worries on lack of curve for reaching his prostate.
