I can relate with you (especially all those pics on tumblr of guys with huge dicks).
What I can say is....don't get so caught up in the time on T it took them to reach that size. I used to get bummed about it, but now at over 1.5 years on T I'm still pleasantly surprised by growth
. Don't compare yourself to anyone's time scale.
People say pumping and DHT cream works, but I haven't really tried either in depth and DHT cream is illegal where I am anyway :\. There was a study conducted on cis men and penis enlargement and they found that "traction" techniques worked best, but I'm not sure if we HAVE traction techniques available for our anatomy (if you know of any please share xD).
I think labial pumps may be useful as well, considering the majority of our erectile tissue is hidden back there, but not many people have written about this.
