Some people love really hardcore whips, floggers and things like Bull Whips. Others prefer something a bit more tame, softer and more within the "sensual punishment" realm. Personally, I enjoy softer leather whips which are great for spanking, flogging, or "punishment" of the penis, pussy, breast or thighs. Erotic spanking is often more popular than "discipline" spanking and for those activites, these types of flogger/whips are best. :)
