As I read around the net, I find that many people have problems getting vibrators or dildos. Some, like me, don't have an electric toothbrush or a removable shower head. I also find it hard to rub myself and have an orgasm.
So I ran to the bathroom, emptied out an old shampoo bottle, filled the water up, filled the shampoo bottle with water, placed it directly in front of my clit and squeezed. The water fills up automatically underwater, so I never had to stop and refill.
Something else I do is lay down in the bath, prop my legs up like a butterfly and slide under the bathtub faucet. Wow, it feels amazing. I guarantee you at least 5 orgasms in one hour.
Hope it helped. (:
