"No Sex Allowed"

I had an appointment with my OB/GYN today who did an ultrasound to check my innards and see if there was anything to be concerned about. He also wrote out a "prescription" for my husband to get his semen analyzed, and a referral to a radiology diagnostic center for me to get that HSG test next Wednesday.

Things I Didn't Know Before Today
1. That I wouldn't be able to have sex between now and when they shoot the dye up into my body
2. That there would be some "dye leakage" and bleeding after the HSG
3. That they would recommend a mild pain reliever before the procedure
4. That I have a small, tiny 2 cm cyst on my left ovary (doctor says not to be concerned about it at all)

Things I Still Don't Know
1. How they're going to go about getting semen from my husband (will a nurse named Vanka or some such be "assisting"? Will pornography be involved?)
2. How badly will the HSG hurt during and aftewards?
3. What color is the dye they'll use? Will I be leaking neon green all day?

Kitten update: Two nights ago at a dinner with friends, my husband said for the first time affirmatively that we are getting a kitten! We've made plans to go and pick her up next Tuesday. Yay!

UPDATE:
1. My husband was able to "produce" at home and bring the sample in.
2. The HSG didn't hurt even a speck. I felt like I had metal in my mouth all day, though.
3. The dye was clear; lots of leakage, but it was all invisible.
