New Year based on my experience and reading stuff on this thread (YEARS of research then
) DTD itself will not change his intent per se and will not ruin anything that was going to work anyway.
DTD can change how the woman behaves due to the bonding chemicals released by sex and that behaviour can change a relationship dynamic in the early days. Not necessarily instantly but the bonding chemicals flow pretty quickly. For example some women suddenly up the texting and comms, get all cutesy and cuddly and want more contact after presenting themselves as fun and independent so the guy is faced with a new personality when his poor old bonding hormones often take more time to show up. I think a lot of guys clear off when faced with this wondering why she's had a personality transplant and the woman, who's oblivious to the fact that she's following her instinct, wonders why she's been 'dumped' yet again...
If he vanishes or slow fades post DTD he was going to anyway.
There is a timing element in terms of finding out whether or not you're compatible but that can take months and months to establish in a new romance.
I say go for it! Hold his gaze and say I'm ready for you to come on too strong then enjoy!
Basically it's not just about the timing otherwise that would be waaayyy too easy! Good luck and have fun.
