Yes. Foreplay play a big part.
And mutual trust/hygiene etc as well

Once I was bonking with my ex, and when switch position, due to too high, poke the wrong hole... Worst part is that we were doing some light bdsm (Her mouth stuff with one of those thing (Can't remember what it called), hence she couldn't shouted in pain. For me, as my dick contain her love juice which act as lubricant, plus do felt quite tight, but thought it was just cause of the position, and legs together... Hence did no think that poke the wrong hole, and continued to bonk till cummed...
