Yes it can easily spread via sex. But it can be spread via casual contact too, similar to chickenpox. Fortunately we already have a vaccine that prevents it, the smallpox vaccine, which was given to all children at birth and then at age 10 or so in the US until 1974. (A little bit later in Europe, well into the 80s in Latin America, and into 2000 in China.) Got a vaccination scare on your shoulder? That's from the (live virus) smallpox vaccine. (Today's vaccines are not live virus and do not cause a scare.)
It spreads nothing like chickenpox.
If the average homo was having sex with less than 1 new person a week then the virus would soon stop spreading
The longer it continues spreading the more likely it ends up in an immunocompromised individual where it can mutate into a more virulent form.
Good luck with your rainbow flags when people start blaming gays for this if we have another lockdown.
