Its not so. Things like this differ from person to person. One of my friends is a "purist" of sorts (a term coined by herself) i.e. she doesn't use any toys at all. Though i admit that i'd prefer a toy which is just shaped like a phallus but doesnt have detailed inscriptions (blood vessels) or contours which resemble an actual organ. Most of my friends share my views. Though i've also known a few who like their toys to resemble the male organ more closely, and it's just for fun.
Not at all...why would you even think that?
Just a quick retort in general, nothing detailed. I for one enjoy being penetrated, after all I have a vagina why not let it get some fun? One of the reasons I love my (ahem) gf, (who says we are, ''semi-attached,' whatever that means,) using her strappy on me is that she knows how to use it.
I think a lot of it depends on to some extent why someone is lesbian. I love penetration and have always loved a partner who likes to use either finger's dildo's or Strapon's
