Nope. I have only had my exes and husband available for practice. I am a firm believer in talking during any sexual act. Well, while I am going down it is really more them talking than me, never talk with your mouth full. I tell my man to tell me what he wants because every guy I have been with is different. Some like it long, deep, and slow while others like it vigorous, shallow, and sloppy. You can't get direction from a dildo.

Nope

Same here, done it because I was asked as a tease. Can't really see how it would be very helpful practice if I couldn't get any feedback...
