It does take a little pressure off, keeping it to yourself! There's nothing like parent/inlaws/friends raising their eyebrows every time you say you're a bit tired, or your tummy is poking out a bit more than normal (note to people who know people TTC - a poking out tummy happens for reasons *other* than being pregnant ...like lunch!) ...you know the drill.
It's funny how close you get to the community here, and I guess on other message boards if you visit more than one. The sharing of information is good too - being able to say to someone, without feeling silly, or embarrassed "Hey ...have you ever had ...?". Makes a difference.
I think my DH feels a bit like you ...I get it mostly out on OB, and he can continue crusing and enjoying the ...er.... better part of TTC!
He said to me, ages ago now, that he was secretly hoping it'd take a while so that he could fill his boots with ....er.... ahem ...you know

He said he'd have felt really ripped off if we'd fallen straight away

Ahhhh ...bless!
All the best with TTC and I'm really glad that OB is doing the trick with things!
