Ouch. Given how early this was detected, you should have been offered an antiviral, probably Aciclovir, to use for five days. Outbreaks should decrease in frequency over time, and again, using an antiviral as soon as you feel any tingling usually reduces severity.
It is a tough one. On the one hand, most people have at least one strain of HSV already, usually HSV-1*, including anyone who's ever had a cold sore on their mouth, and you can't give someone it if they already have it. When testing for HSV-2 became available about twenty years ago, about one in eight female blood donors - i.e. people who'd been screened for behaviour considered risky, including being a sex worker or having a bisexual male partner - and one in four women attending a sexual health clinic had HSV-2. Not everyone knew it, because it often doesn't have any symptoms.
On the other hand, you do know...
Is saying something like 'like most people, I have had..' on your site / profile an option?
* I've had HSV-1 since I was a child.
