A few months ago I made the mistake of starting out large with Doc Johnson's Jenna's Loving Touch vibe. (link). It's way too large, bumpy, and lumpy to use unless I'm very worked up. The curve at the top adds about another inch to the diameter! I would love a slight curve for some g spot action, but then again something "flared and tapered" sounds appealing as well. Which do you recommend and why?
