I've just ordered myself a 
chastity belt
DH often goes away for work for a couple of days at a time - sometimes more - and I really get turned on by the idea of being strapped in... so I've ordered a chastity belt and next time he's away I'm going to ask him to lock me into it... So I feel like such a perv. But I suppose I am... 

aren't I?
And he doesn't know about it yet, either. Yikes!
