You deserve to feel good when you're masturbating or having sex, but if you're having some trouble getting there, an arousal gel, serum, or oil can provide you the boost you need. While these aren't exactly magic, most arousal gels increase sensitivity wherever they're applied — think the clitoris, vulva, or nipples for starters — and are formulated with ingredients like menthol, peppermint oil, CBD, and arginine to create intense sensations. Once your sensitive bits are well, more sensitive, it can be easier to reach climax (if that's your goal).
