I know that this hasn't been replied to in a while but I wanted to share my experience.  I attend a shul in a small southern community.  I attend minyan three times a week, wear a tallit, wrap tefillin, wear a kippa full time.  I don't pass 90% of the time but no one bats an eye.  I even go to breakfast with the rest of the guys after minyan on weekdays.  I have taken an aliyah on both Shabbat and  weekdays.  Really no problems at all.  There is a person that attends Shabbat services and while I have no idea how they identify themselves they have a male name yet wear makeup and female clothes. I haven't seen them be asked to take an honor on the bima and don't know if that is their choice or not.  I haven't seen anyone bat an eye towards them.  It is really no big deal.
I suspect that the rabbi knows the deal and included you as a son.  I don't know the make up of your community so I couldn't say for sure but generally speaking reform communities are pretty liberal.  If there is a renewal community near you, you could give that a try too.  
Hope all is well for you and Chag Samech Purim!
