vaseline as a lube for TTC girl???

Me and my DH have used vaseline before as lube before. Just wondering if this would be bad for TTC girl. Sylk makes my ph go up to about 6.5.....way to high. I need to figure something else out. What about ky jelly? is there anything besides canola oil??

I would NOT use canola oil. It's pH is in the 6's.

Astroglide is better than KY but KY is ok too. I am not a fan of vaseline because it doesn't break down in the vagina and stays behind and causes all kinds of trouble, and I'm not sure how it will react with the other swaying things.
