Nothing in any natural flesh tones for me, too creepy. But semi-realistic shape can be okay, if it's a suitably obnoxious and unnatural color and offers me some incentive to try it. I think my most realistic looking toy is the Fun Factory Curve in bright purple, so not very realistic, really.
For a long while I preferred abstract dildos. Then, I purchased my first realistic dildo, and I fell in love with the feel of it. I also fell in love with how turned on my partner got while watching me use a realistic dildo. So now... I kinda like both.
Abstract--I am actually turned off by realistic looking ones. I feel like I'm masturbating with a dismembered body part--I know that's gross,and I mean no offense to those who like the realistic ones; I can see why one would like them, in theory. They just are not sexually enticing to me at all.
Abstract, definitely. Realistic ones creep me out and I like my sex toys a little bit fun and silly to be honest! I can see why people would like the real ones but it always feels sort of morbid to me.
Realistic all the way, the more realistic, the better. I LOVE veins and testicles (but hold the paint and fake hair, thanks! ). I have some bi desires, but no interest in being with anyone other than my wife. The best realistic dildos, like Vixskin and Cyberskin, are enough like the real thing that I can pretend it's a real part of my wife!
