The first year is the fun one. Then they get ugly with surgeries, poking, prodding, drugs, self-administered shots, and generally take all the joy out of conceiving. Though since DH offered up his boys for general surgery and had them swell to the size of grapefruits, he does have my undying love and devotion. He definitely took one for the cause.
Usually the first couple months, just enjoy it. Make sure your stuff gets in the appropriate hole. That's a tough one for us. We like alternative areas for that and/or I just love to watch it. Later we found out the swimmers just aren't there, so we stopped worrying about it.
You can have some fun learning to check her cervical mucus/cervical position. The egg white consistency stuff is the "hey, I'm fertile" sign. Cervical position is where the cervix gets high and open to let the swimmers through. Also, charting her basal body temperature can be fun for a while. www.tcoyf.com has the play by play on all of that.
There's some good scenes you can do if you're the sub and she's the dom since she can be aggressive and "use" you as the sperm donor. Dress as a nurse and take the semen sample vaginally, go praying mantis on you and threaten whatever snuff turns you on after she gets her sample, etc.
I'd lay off the CBT and hot tubs and cut back on smoking if you smoke, but the avoiding tighty whiteys, all caffeine and hot baths are myths. And while the every day, twice a day sex is fun, every other day can be better because it gives the swimmers(and each other) time to recover.
The main thing to remember is it can take a normal couple under 35 one year to conceive, but many conceive in the first 3 months. If it takes more than one year or more than 6 months if the woman is over 35, then you should see a fertility doctor and let the poking and prodding begin.
Have a great time, good luck and baby dust,
