How to avoid O when DTD??

Title says it all...
Havnt had an O at all for about 8 weeks now...and though im not one to always O, having gone so long is getting very...ummmm...tricky, because the way I'm feeling now DH just has to LOOK at me the right way and it almost happens...

All throughout tonights DTD i was concentrating really really hard on a complex nested formula, and some macros in an excel spreadsheet at work....but god it was hard!

Any suggestions? I hope to get another 3-4 attempts in before Ovulation, so its gonna be tricky.
Can I have an O once I'm in the 2ww....or best not to? Ive been avoiding O since i started the sway with my diet, so 8 weeks.

TMI, but we did a lot of the prep-work on DH before we began DTD, so there was less time for me to start to enjoy it!

Go Lassie!! or should I say go Lassie's DH! LOL, I'm impressed. I think the only thing you can do is try to have your mind elsewhere! Although I have to say I actually think its helpful that your enjoying it, I feel if your all tense and stressed your less likely to get a bfp. Don't know if theres actual fact to back it up, but it certainly seems like it!
I on the other hand am like just do it inside me already LMAO!:rofl:

I think that right after O you need to DTD a couple times to "clear the pipes" LOL and then back to not Oing.
