Try actually answering what was asked or is that to difficult for you ?
the expression "suck my dick!" been around for a long time. apparantely some people add to the insult by even showing their dick.
now there's a few things you can do to handle the situation. here's a few verbal responses:
"not now, cant you see im eating! maybe for dessert"
"thank you kind sir, thats a very generous offer, but as a married man i have to stay true, that would be considered cheating"
"only if you bend over first (no homo)"
or
you could turn it around on them showing YOUR dick - "howabout you suck mine, bitch!" (this doesnt work if your dick is smaller)
or
you could wipe out your dick and say "how about we have a sword fight instead? en garde!"
or you could just walk away.
so as we can see here, there's plenty of other options than fighting the guy.
