There has only been one dream for me, which wasn't a sex dream per se, it was a nightmare and somehow my T popped up and calmed me down through sex (which worked great, nightmare stopped...). I don't have lots of nightmares though and this has only happened once.
Thoughts while I'm awake happen more often, T has said it's normal even if there's no romantic/erotic transference and no attraction. He said as long as it doesn't interfere with anything and I don't feel like it bothers me, it's fine.
