sex with short cervix

I am 27 weeks and diagnosed 4-6 weeks ago with short cervix. By now I'm probably less than 50 mm. Steroids, progesterone, no vaginal sex...but...
Is clitoral stim out of the question? I know it's not the end of the world, but I am really feeling the need. Can orgasm really cause my cervix to contract? Wouldn't mind if hubs and I got some time together.
