Orgasm in Pregnancy

Is anyone else had a hard time reaching orgasm in late pregnancy??? During the rest of my pregnancy it wasn't to hard to get the big O but this afternoon it took a lot of work. Like hubby tapped out and my arm ached after using my toys. I had a strong contraction when I finally reached orgasm but it was a weak one. Totally lame!!!! I'm hella horny but ain't worth it if it takes this much effort and it's a little reward
