If I were 20 again? I suspect that much depends whether you mean in 1981 or 2015!
1981 - I'm not sure that I'd change much. I wouldn't stay single (hated that). I would try to spend more time en femme (maybe move further from home to facilitate that) but probably no more than evenings and weekends. Still wouldn't be attracted to men. Would definitely have told any potential wife before marrying.
2015 - Still wouldn't stay single. Would definitely spend much more time en femme - probably not at work but definitely more than would have been comfortable/practical in 1981! Would probably want 2nd date with any GG to be en femme and still only interested in GGs!
