Is it possible for a guy to be allergic to vaginal fluid (discharge)?

I think it is possible to be allergic to anything so don't rule it out. But without being to intrusive, what is your pubic hair like? Are you sure it is not a rash from that? I know my boyfriends facial hair gives me a rash on my breasts etc if he has been spending a lot of time there so I suppose it works the same with your pubic hair touching his face. Maybe the other girls were shaven or had 'let themselves go' and it wasn't as prickly. Just an idea
