In my case it was used mainly to prevent me to be stimulated here by Emilie,to try to make me less interested by giving sex to her,as I can't get nice feelings on my breasts with it on(which make the frustration even worse to manage,when I give sex to my girlfriend).
They may like it reduces my possibilities to feel sexual nice feelings on my breasts more generally too,but it's not the main purpose(but I don't have to wear it permanently,I think this purpose apply more for permanent wearers).

I agree with @Angelina,it is effective to prevent us to get any nice feeling here...🙁
And it is hard emotionally,too.
