Hi all, 
I'm a typical cuck. I'm straight and spend most of my time walking around with a little hard-on that is never relieved by my wife, as i'm denied. My only release is through wanking.
Just lately i've been viewing a lot of sissy threads and videos and am starting to have my 'head turned' a little. I buy all of my wifes underwear for her but yesterday bought some for myself as well 

 I wore them for the first time last night (wearing my cock cage) and it felt great. 
I've noticed that in a lot of the sissy videos the sissys are cumming while being fucked in the ass. I'm assuming this is because of their prostate being rubbed by a cock head, is this correct ? What does it feel like ? Again assuming but i imagine it's rather nice.
Also, and i know this is a bit gross, but how do you clean yourself out 'down there' before being fucked ? (sorry to lower the tone !)
I don't think i'll ever go down the route of letting some bloke fuck me but would like to explore using one of my wifes dildos.
