Very good idea with the pillows to support you for rear entry...... (he he he)
I used 5 pillows!! It was good for support...... and while we are talking about it when u r DTD with your pillows underneath... it helped that I gave myself a bit of a tickle while we were DTD from behind....
OMG i cant beleive I am typing this!! HE HE HE....
I found it helped sooo much to relax the muscles on the inside and made it very very very much more enjoyable for me

Good luck honey
