I have DP with a man in my ass and a dildo/vibe in the other.. I just bought 2 vibes and I use them both while masturbating now.. I put the larger one deep inside me, turn it on full power and use the smaller one on my clit.. I know that has nothing to do with DP, but I enjoy having 2 objects going at once.
sure don't. Hell, I don't even own two toys designed to be used internally. But I'm not big into anal and I don't use my toys internally, I vastly prefer just having vibrations on my clit durin gmasturbation.
