Ok. I'm going to tell you guys how I got my boy. What I did different. It might be TMI, so be careful!
I have always liked DTD better when I'm on top. After a few years I changed & the possy we were doing alot was doggy. Told ya TMI! Anyway as far as I know its the male sperm that are lazier (go figure!)

Also with the girls it didn't take too long to get UTD. With Jesse it was like 10 months of TTC so for a month we DTD every night.
Next month I got my BFP. My little man!

HTH...if you were game to read! Good luck!!
Either way just have fun practising!!!
