Ok, this is mrs. Banditman, lol. The circumference of our son's head was 18 inches, I had a level 3 episiotomy. Our daughter's head was only 15 inches around, so I didn't have to be cut. After our daughter, things were way different, no pain, no problems. If you had an episiotomy, i'd say have a gync check you out before you start having intercourse again. Also, do a little exploring on your own. If a little pressure on your scar hurts, you're not ready yet.
Now, as for making him "take matters in his own hands," there are alternatives. For us "bigger" girls, use what I call "thunder thighs" ie clench your legs around him. If he gets the angle right, it'll work for you, too. Oh! He's reminding me to remind you to shave first! Rofl!!
Good luck!
