What to use when masturbating?

I have this thing where sex is really painful for me. It's an actual disease and it sucks. My doctor told me I was supposed to massage the insides of my vagina daily. I swear to y'all I'm not making this up. So...please tell me something that would help me get used to this pain or ease it because I miss having sex...I miss it a lot actually. I'm not really into using my fingers. Anything else...
