Yes, I've read a discussion on this on, I think Quora, where someone was asking why a therapist didn't offer a tissue. And some T's who responded said they were trained not to do that for the reason you said, that it could seem like they were trying to stop or control it. Plus because some people are self-conscious about it, it would seem like the T is drawing more attention to it.

Lostislost, if that's something you feel you'd want, maybe you could ask your T about it? Or at least wanting him to comment on your crying.
