I've seen the question asked by several people if there are inordinate amount of frum people with sexual addiction issues. I usually say no and offer the many reasons that we can all come up with that may appear that way. That being said relationship and sexual issues are a huge problem in frum communities and the more the communities are "frum" about these issues the worse they are. So does anyone stop to think for one minute that maybe the way we separate women only feeds into these problems. I know I'm wasting my breath. 

Anyway Chaim there is a bigger issue here in my humble opinion. The fact that your yeshiva doesn't allow it means you would have to go around their rules in order to interact with girls and hide this fact from them and perhaps from your family. To do that would be dishonest and duplicitous.  Sadly our current system ends up breading dishonesty and duplicity in sexual matters that can and does  nebach carry over into marriage for many people.
