This shockingly powerful botanical formula creates a warm and extremely unique buzzing sensation that awakens the nerve endings, increases blood flow and makes a woman feel more sensation than ever before! Using On Arousal Oil will help a woman's body respond more easily to physical stimulation, and give her the type of full-body awareness that raises her arousal level. These two things give women the ability to achieve orgasm easier. Another wonderful benefit of On Arousal Oil is that it may actually help some women increase their production of personal lubrication. This may be extremely helpful for women going through hormonal changes, hysterectomy, or taking medications that tend to decrease their body's ability to self-lubricate. On Arousal Ultra is for advanced users who love feeling the ultimate in sensation. It is the absolute strongest, most intense formula.
