Ok...i'll give this a go.
Somehow it seems alot more intimate, knowing not too many women will let a guy do it to them makes kinda special knowing that he may not have experienced it with many other women but is with me. Physically its alot tighter and because of that i feel it alot more, in the sense that it can be more painful and i can feel everything being stretched and worked.
Also the fact that it fits into the catagory of...naughty
The down side it the preperation and the mess, which makes it a not all the time thing
