Well, as promised I am back with my report ... and ... I have some good news and some bad news.
The bad news is that there must be at least one exception to evey rule - and I found it. No difference to report here; afterwards I checked by asking my g/f, and she said she couldn't feel any difference from one side to the other (but she DID enjoy it! Oh well ... )
The GOOD news is that it was a helluva lot of fun trying!!!

. Send me on a mission like that any time SexGoddess!
