"Derek’s eyes flash red in the semi-darkness, shiver running through Stiles like a feather-light touch at the heat in his glare.
“Come on, big guy,” he taunts, still breathless. “I’m not done with you yet.” Derek rumbles in his chest, deep and compelling, and Stiles tucks one heel beneath his ass and lets his knee fall to the side, spread and waiting."

An alpha biting a human puts the werewolf saliva directly into the bloodstream, i.e. 24 hour werewolf turnaround.
an alpha having sex with a human, however, takes much, much longer, because skin absorption of alpha saliva just isn't potent enough.
Derek was never meant to be an alpha, he never got the full explanation on how to make a beta.
Stiles is just really excited that his boyfriend can neither catch nor transmit any STI's.
The restlessness around the full moon is kinda weird though…
