my period cramps were killing me. I posted for help on line and told hot water bottle and heating pad.
Did not have heating pad, so I used a milk jug with hot water. That helped some, so I took a plastic water bottle and filled it with hot water. oiled it up and stick it up me. That burned like hell. Pulled it out and let it cool. Stuck it back and noticed the bottle feels good going in. I fucked my self with the bottle and my cramps went away.

Try it some time.
