We usually use the Wahl for vibrations when I feel I need to come. We often do not turn on our vibrating phallic shaped toys. I prefer the vibrations from either wand vibrator-massagers and the spot vibrations from good quality pocket rockets and bullets to warm up.
So, a lot of the time, we use our insertable vibrators as dildos. I like the feel of nice sized penetrative toys during oral sex, wand vibrator play with My Man and when I'm alone. Sometimes they are turned on, but not all the time. If my husband is going down on me, I find the vibrations interrupt my ability to feel what he is doing.
We found there is a much better selection of sizes and shapes in penetrative vibrators than in dildos, and you have the option to turn them on if you want. So, you get the best of both worlds with a well shaped vibrator even if you don't turn it on all the time.
