I am 35 weeks pregnant and my husband is out of town for almost two weeks....I am thinking it would be nice to have an orgasm, on my own...but is it to close to due date to masterbate?

I can't see why it would be at all, your ownly touching the insides of your body not beyond the womb.

I am more concerened that your husband has to be away, are there people around you should you go into Labour soon?

Provided your pregnancy is "normal" and you havn't been advised to refrain from sex, I don't see why this would be a problem.
When I was pregnant with my daughter my fiance and I continued having sex until the very end.
I'm 24 weeks pregnant now and quite frankly will remain sexually active unless my O.B tells me otherwise. For alot of women, myself included pregnancy puts your sex drive through the roof.
So unless you doc has said sex is a no no... relax, go nuts...and Good Luck..
