bicycling and herpes

I am a 57 year of woman who contracted herpes from her partner about a year ago.  My initial outbreak was severe and painful.  I had no other outbreak for 7 months, but in the last 4 months I have had six outbreaks with little time inbetween them. The episodes last two weeks. These outbreaks continue in spite of taking daily acyclovir  I began bicycling more about that time (the weather improved), only cycling when I was inbetween episodes.  I am wondering if the bicycling and rubbing on the seat can cause a new episode.   Some of my rides have been quite strenuous and I was exhausted afterward.  Can lots of physical exercise cause an out break? I love bicycling and I hate the idea of having to give it up!
