It very much depends on the woman. My ex wife was very, lets say traditional in bed and toys were never part of our sex lives.
The next long relationship I was in was with a very highly sexed woman who found it hard to cum. We often used various vibrators, sometimes a huge thick "realistic" one which she couldn't take more than 8" of, sometimes a small one in her ass while I fucked her, I have a close up photo somewhere of her with the last inch of a 2.5" thick, 6" tall glass sticking out of her pussy.
Other women have been rather more conventional. a few have liked my cock ring which makes me a lttle extra hard and, more importantly, holds the skin of my cock tighter. My current girlfriend is very into sex but everything has to be rather too spontaneous for toys to be involved. Only last night we tried a vibrating durex cock ring which I was enjoying but she found too distracting. I had to remove it but it played a small part in the best fuck we'd had for a while!
