Suppose my situation applies to to expalin:
My awarness for adult play things was far more mature than my OH's. I found her hovering around the 'Durex' related isle at pharmacy. Took me by suprise, but I thought I'd entertain the idea and browsed with her. She picked up a vibrating bullet. Initially got me a little excited, possibility of exploring and I suppose we entertained and eventually purchased the item based on being able to enjoy 'another' experience - granted more here than me.
First use, I admit, I felt very weird, especially with her reaction. For me it was and still is a little hard to accept that something else could provide pleasure for her, but seeing her reaction overwrote any feeling I had on it.
Honestly, if the vibrater was larger, I think I may have found it difficult to take on board.
I think it can be a welcomed addition in the bedroom so worth considering telling your OH if you feel the item attributes wouldn't affect his opion on his.
