Some peoples who transition are getting too far in the stereotypes of their gender. For ftm it sometime result in mysogyny (hopefully it's far from being a general behavior).
If you're confortable with yourself actually, I don't see any reason to stop dating. Ofcourse, it's a bit more complicated without the surgery as you're gonna have to explain everytimes. If your date doesn't involve anything sexual it might be good to get rid of your social anxiety, just don't let the bad comments pull you down.
I started dating after 1 year on hrt (no serious date before srs). It helped me a lot to have comments, I learned to drop my "too much" and look at myself differently. I decided to wait srs before serious dates because I didn't feel like explaining all the thing to them, but it's personal.
