Ana's post and the NIC summary mention what is usually unmentioned: sex during TX. Just like you use a crutch when you've injured your ankle or leg, or a brace/sling for your arm, consider some assistance during this period. Based on my personal experience, (backed up by Internet porn videos)
Guys are easy: we are just like old Model T Fords, prime the engine and just grab hold of the handle and crank it up. Eventually the engine turns over. (Note: unlike the instructions to the Model T, it is not necessary to use just the left hand and turn to the left in order to avoid having your arm broken). Soon you can resume normal driving
Gals are more complex but here a vibrator is a girl's best friend. The gold standard is the Hitachi Magic Wand, which look big and needs to be plugged in but is magic. Avoid cute nternet substitutions. Bonus, it's sold as a back massager so not embarrasing store or boxes.
Enjoy
