Vibration controllers in a dildo that is meant for thrusting would just be a hassle since I don't care much for vibrations in the vagina. Plus silicone is always the best (unless you want something hard then pick glass or metal).
just wondering what the ratio is on dildo vs vibrator
We recently bought the Brandon Lee Sensafirm Penis Dildo and have found that it works better than any vibrator for penetration. It's not hugely long, 8 inches I think, but it's very thick. My wife found it difficult at first to get comfortable with it but when she did it was amazing. She had a huge orgasm while I fucked her with it, making her pussy foam. And even though she was tender afterwards she said she had experienced a really intense orgasm, not that there was any doubt. It can be used solo too as it has a suction cup at the base that will stick to practically any surface including walls, doors, tile, plastic and timber. AND it's stocked right here at EF. Check it out before you buy!
