Do i have touble in the bedroom?

when me and my partner gareth have , when i come it makes me have a type of fit, i usually start by rolling on the floor, then i get up uncontrollably and shout whooooooh yahhh thats sooooooo good and then begin to cry in the corner i have no idea why, anyway it always ends up in a big mess of whitness all over the walls, me, gareth and the ceiling (dont ask me how it gets there). meanhile gareth just lays there. does anyone else have this?
