HELP!! Does depth of release matter?
Some people advise shallow release for pink and deep release for blue. Does this really matter?
Probably not. Reason being, sperm can swim, and semen and CM are kind of like little "life rafts" for sperm to help them stay alive till they make it to the safety of the cervix. Pink sway tactics dry up CM and lower sperm count (so fewer can make it to the egg to begin with) and blue sway tactics improve CM and raise sperm count which will hopefully increase numbers of sperm at the egg, possibly swaying blue that way.
If you are a pink swayer and doing a ton of stuff to dry up CM and lower sperm count, shallow release may make it too hard to get pregnant and so it's best to give it a pass. You've already done what you need to do to lower sperm numbers, and so shallow release is just overkill.
If you are a blue swayer and doing a ton of stuff to make good CM and increase sperm count, you don't need to stress over having DH release really deep if it's painful to you or just not your preferred position. (Most of us can't O doggy style and having an O may help sway blue a bit.) Just have him complete the transaction in whatever way works for you as a couple, stay laying down for 15-30 min afterwards, and go about your business.
In the big picture, if you were doing nothing else to sway, depth of release might sway a miniscule amount, but it's completely meaningless in an otherwise-good sway.
