A butt plug is hardly a big deal but I get your point and I do agree to an extent but what I don't like is when we start talking about women (or men for that matter) as some kind of separate collective with a hive mind, they like us are independent people with the ability to think/feel differently to everyone else, I feel it's wrong to assume because I am a man that I know how every man feels, the same goes for women, I don't think we're giving individuality enough credit here.
Like I said not all women feel the same way as Sarah does, not all women's boundary for sexual 'exploration' is going to be the same (the same for men), and certainly not all women feel like they are being 'invaded' by the wang during consented sex, there are women that do actually enjoy the sensation believe it or not

, women that don't feel that they are being 'exploited' by the wang, women that actually welcome the wang now and again, some that even demand it


, we're not living in the 1950's any more.
Take anal sex for example, that has always been a controversial one, there a some women out there that will argue that other women only do it please the man thus being unwillingly submissive due to pier pressure or fear the results of not giving their partner what they want, but actually type "Do women enjoy anal sex" into google and have a good read from many women that have very interesting contrasting opinions on this topic, you may be rather surprised, I was when one of my ex's actually asked for it, no hint from me at all, in fact to this very day I think she was waiting for me to ask so then it would have seemed like she was doing me the favour when actually she enjoyed it.
Although there is no doubt that men and women as a divided group have their own collective understanding of each other and common grounds I think on both sides of the camp men and women are becoming more independent, more people are stepping outside of the 'gender' box with more 'masculine' females and more 'feminine' men it's harder to judge a particular sex collectively these days, I think it's an inevitable part of the human evolutionary process leading us into a more androgynous future.
