I am usually a bottom, 'cuz my thickness is about 6", shaft AND head,,,
A bit intimidating. If aimed at someone's point of entry.
(I also love someone who does get that prostrate-feel, while I 'bottom', gets me riled up!)
I'd love to do the same, , , gently, that would give 'the bottom' the same pleasure....
....haven't had much chance for awhile....
