Well, there is no "yes or no" question to this question. I believe that this is a very personal question that only you can answer.
I would not be quick to judge the guy nor would I blow him off just because he has genital herpes. As a male with genital herpes I can tell you that having it has been an emotional roller coaster for me and has caused me great emotional stress especially while dating trying to find my mate.
I know the stress of having to tell someone you have it and that alone is very tough to do. Let me say right off the bat that I am no herpes or std expert but I have spent 100's of hours researching the subject. I have read about, and actually know quite a few couples where one has genital herpes and the other does not.
In all of the cases none of the relationships seemed to be affected by one partner having genital herpes. I always had coldsores my whole life and not once did I give it to my spouse in the 10 years we were together. I believe if you really care for someone then this is not a big deal if you protect yourself. An ounce of prevention is worth a pound of cure.
I kept her from getting cold sores by simply not kissing her while I had an outbreak. She had mentioned to me several times that she wished she had cold sores because she couldn't stand not being able to be kissed by me. I told her that no matter how much I loved her I would prefer not to give it to her and she never caught it in all those years.
If you really care for this man then you need to know that even with the use of condoms you can be infected with genital herpes. I recently saw that a company was producing condoms which also covered the scrotum for extra protection against STD's.
I don't want to scare you into thinking that just because you have sexual intercourse with an infected male will mean you to will be infected too. Remember that there is plenty of time in between outbreaks that your chances of contracting genital herpes is slim to none.
There are plenty of places to get information about herpes in general but since you are wondering whether to date a man who has genital herpes then I suggest heading into some Herpes dating forums for the answers.
Www.herpesdatingsite.biz is one of the best places on the web for herpes dating.
