Also. Not to be crude, but have you readers...seen enough sex or read about it?
When you're really into someone, you go all out. Of course it's gonna be messy, when you love someone you don't give a flying fuck about being technical because you want the person you're with to feel good.
Like, it's funny that many read yuri, think they know how two women do it, and then proceed to complain that it's not "enough" for them.
