Peak day..bd and hubby doesn't cross the finish line

Tera
It's peak day and we bd for +45 mins today and DH could not finish, would get to the brink and "lose it". it happens every once in a while say after a night out or dehydration but that wasn't the case.. He didn't want to give up but eventually I said let's try later. Vivian (my lady bit) was getting tired! But it's peak day!! I guess we can give it a go later.. But it sucks, and I try not to take it personal but come on!!!.. I guess pun intended.. 4th month of ttc, and I don't have to tell you how much pressure a day like yesterday can have. All of the questions..
