Obviously, epilepsy might be impacted so yes, definitely check with your doctor before trying anything but it sounds like you are planning to do this.
If he/she gives you the go ahead… I have the Estim KIX Beginner’s Kit and using the pads I think this is a great intro, it’s a whole new sensation both independently and combined with your regular masturbation techniques. I also have a probe but didn’t get as much from this as using the pads though posdibly because the power output needs to be greater for me. My full review is here if you fancy a read.
