Another thought I had was that your seat may be too high. I had a similar issue as you when I first started riding and when I went to be fitted the guy was amazed I was able to ride at all. My hips were rocking from side to side with each pedal stroke and thusly smashing my lady bits to pieces in the front. You can always try lowering your saddle and see if it doesn't help. For me, it was instant.

Also keep in mind you can put chamois cream up front too to keep the irritation down.
