adapting toys for increased sensation
Most people with hypersensitivity find vibrators to be very unpleasant. They just provide too much stimulation. Remember that sex toys are just toys, and are a matter of taste and preference. With hypersensitivity it is best to get a toy whose movements you control. For example the non-vibrating insertion toys for men can provide intense stimulation just from having them around the penis (all about the fleshlight).
Homemade toys can be tailored to provide just the amount of stimulation you need. Paintbrushes are ideal sex toys as they come in different shapes, sizes and textures, are easy to use, can be held in a hand, mouth or foot, are inexpensive and easy to clean.
