Can a guy c*m two times?

Answer 1

After o****m, a guy experiences what is called a refractory period during which he loses his erection and continued stimulation will neither maintain the erection nor feel good. In pubescent boys and young men, the refractory period can be as little as five minutes, but as men get older, the refractory period increases in length.

So yes, a guy can c*m twice (or more), as long as there is sufficient time in between to account for the refractory period.
