I like both a lot. I love glass toys (which are usually unrealistic) and I love my VixSkin toys (which are usually realistic). So it just depends on what kind of sensations I'm looking for in the moment.
Doesn't matter too much to me, but when we're talking hairy balls realistic... NOOOO.
I can't find it, but I've seen one on here with some fake hair on the balls or something.
I don't even want balls on mine. But the way the head is shaped in realistic ones feels nice, so, I'm all for the shape, just spare me the visual details...
I really hate realistic dildos. They're very unattractive to me, and usually large and just useless for me. I use my partner for sex, so a dildo wouldn't be handy. I stick with non-realistic vibrators and glass dildos only -- use em' for foreplay fun.
