Based on the little you've described about this person, he sounds like an immature douchebag ass-clown.
You are judged by the company you keep.
If that's the sort of person you aspire to be seen as, knock yourself out..... As long as you don't hurt anybody else.
And that's where I have another problem with your "alpha" friend.. (p.s. the whole alpha idea is bs. Look up the episode of Adam ruins everything, where the origin of that term is explained and debunked)... Being a "dog" and not caring about anybody else. What lengths do you think this POS will go to, just to get his pecker wet? How many lies? How many people will be hurt?
Chloroform that fool & get him to the vet to get fixed.
Or... Snuggle up with him, follow his lead, and wait for the impending police responses/sexual assault charges/violent encounters....
