I am a first time mother..about 36 weeks pregnant and I seem to be having this "weird" feeling.?

hope this helps, with my first pregnancy I had no drive at all I could have gone all 9 months with out it and been fine but I felt bad for my husband so about every other week I would force myself to do the deed( lol) & I think what you discribe is how I felt I couldn't wait for it to be over sometimes I would make him stop it was just weird! and it took almost a year after delivery to feel "normal" again! but on the flip side I am now expecting my 2nd bundle of joy and I always want and cant get enough of it! go figure! I think it has a lot to do with you hormones as I feel that was my issue. hoped it helped GOOD LUCK
