My boyfriend and I have only been dating for a couple of months but we’ve begun to notice that every time we see each other, it’s almost guaranteed that he has flu like symptoms the next day (fever, aches, cold sweats, congestion) and these symptoms tend to clear up within 48 hours. But then we spend time together again and it’s been a continuous cycle. He’s been sick for a lot of our relationship. He also has ulcerative colitis which is under control but from what I understand, it has suppressed his immune system quite a bit. I also work as an EMT, so I am constantly around all types of people but I, myself never get sick. I do make an effort to shower before seeing him, especially if I’m getting off work. Could I be passing something onto him anyway via kissing/intimacy?
