That’s actually the alt code for an en dash. Em dash is Alt+0151!

I got mine last year. I was fully recovered in terms of physical activity within probably 4-5 days but I did get two very uncomfortable sperm granulomas that hung around for several days each. My nuts swelled up and turned purple so that was pretty fucking scary but it wasn’t anything dangerous. Just a lot of aching. But within a month I was completely back to normal.
