Six months is a long time to wait before disclosing. I imagine he was terrified of rejection. Still, no harm done as you haven't been sexually active with each other yet, just time wasted if you are now not interested in proceeding with the relationship.
I haven't read the whole thread, but there is an awful lot of incorrect information on here.
Firstly, if you are interested in seeing how things progress then you need to find out whether he has genital HSV1 or genital HSV2. This is important as there are reportedly no cases of genital to genital HSV1 transmission. This is because HSV1, although usually presents quite nasty symptoms in a primary genital outbreak, much prefers the face and so the majority of people will only have their primary outbreak or their primary and one or two subsequent ones. HSV2 averages 4-6 outbreaks in the first year after infection. Most people get outbreaks less frequently as time goes on but the rate of HSV2 asymptomatic viral shedding remains significant years after infection. You will need to seek private blood testing (HSV antibodies can be detected in the blood in most carriers) if you want to find out your own status, although this won't tell you where you have the virus, just whether you have HSV1 or 2, or neither.
Some more facts
In the UK around 1 in 10 people have HSV2 (almost all genital).
6 in 10 have HSV1. Mainly oral, although in 2016 (and with similar figures in subsequent years) HSV1 accounted for around 70% of all newly diagnosed genital infections.
The NHS does not test for genital HSV unless you have visible symptoms. Most carriers are asymptomatic or have symptoms so slight that they are missed or visually misdiagnosed. Only 1 in 5 people have classic symptoms and about the same percentage know they have it.
The NHS does not inform people they are not being tested for HSV.
Just because you haven't had any symptoms doesn't mean you don't have it.
Herpes simplex is one of eight herpes viruses. The family also includes herpes varicella (chicken pox) and Epstein-Barr (glandular fever).
Herpes simplex wasn't considered an STD in the UK until the 1980s when a well-known pharmaceutical company in the US developed antivirals and found they could be used to treat HSV and set out to create a stigma. It all kicked off with a front page editorial in Time magazine in the US, calling it the new scarlet letter.
There are lots more facts about HSV. The herpes viruses association is an excellent source of information if you would like to learn more.
