"Do not rub my belly. It is weird and totally not sexy."
"How Not To Make Love To A Fat Girl"
On not being weirdly focused on a certain body part:
On not feeling graceful:
On not making assumptions about self-esteem:
On setting a standard and holding your partners to it:
That last line is so good.
Warning: Explicit NSFW talk of sex/making love/making the beast with two backs/whoopie/f*cking/snuggling/whatever you prefer to call it.
By the way, if you're looking for more information about sex and bigger bodies for yourself or your partner or for both of you, there are some really good resources here, here, here, and here. I also recommend reading Virgie Tovar's book "Hot & Heavy: Fierce Fat Girls on Life, Love & Fashion" for a wide variety of voices speaking on the subject.
