Maybe you're one of those feminists who has to take everything the wrong way or maybe u hate men so much ur blind to anything we say. Read the post idiot I'm asking WOMEN how they feel. This isn't the vagina monologues. Have a wine cooler and relax.
Opinions are funny things, you see, we all have different ones, there is no over riding opinion just because we're female, and you're not going to discover if your woman is rare by asking a bunch of other women if they agree with her.
Testicles aren't something women alone have opinions on either. Men have just as much, arguably more to do with them than we ever will, and further have even more experience of how women react to them.
The simple fact that we can only provide our own personal reactions to them, whereas men can provide the reactions of countless female partners suggests to me, and quite clearly others, that your question would be better placed in a non-female dominated area of the site, so that you may get the most out of the answers provided.
I'm sorry if this sits uncomfortably with you, and you shouldn't take this as a dismissal of your question, but more a concern that you will be better served elsewhere on the site.
Now had you said that your woman was experiencing increased period pains, and nothing you'd tried so far had helped, and asked us to provide some information on what had worked for us... Things may have turned out differently.
