Sexologist Becky Crappsley-Fox has explained how women can reach orgasm by rubbing their genitals against a partner's bicep, backing a viral intimacy trend that has gained momentum online.
Speaking to Metro, Crappsley-Fox agreed that the technique, which has generated active discussion across social media platforms, can indeed prove effective for women seeking climax.
Crappsley-Fox said that masculinity is attractive to some people, with a prominent bicep muscle widely viewed as a physical manifestation of masculine strength. She explained that some individuals may mentally picture the flexed arm muscle as a penis, adding that the size of the muscle can significantly increase its sexual appeal.
The sexologist added that during this specific sexual practice, a woman can stimulate a high concentration of nerve endings. She noted that the technique also allows the woman to maintain complete control over both the speed and intensity of the physical movement throughout the experience.

Sexology is the multidisciplinary scientific study of human sexuality, encompassing biological, psychological, and social aspects of intimate relationships. The human genital area contains thousands of sensitive nerve endings, meaning targeted pressure and friction against firm surfaces can trigger heightened physical responses during intimate contact.
How to practice the technique
Crappsley-Fox outlined step-by-step guidance on how partners should carry out the practice safely and effectively. She stated that the man should lie flat on his back or sit down comfortably, tense his bicep muscle, and keep his arm completely still throughout the process.
The woman should then begin rubbing slowly against the flexed muscle while communicating clearly with the man about what feels good. Crappsley-Fox advised that partners might prefer to keep their clothing or underwear on to prevent uncomfortable skin chafing, adding that dedicated lubricant should be applied if clothing is removed.
Personal lubricants are specialized liquids or gels used during human sexual activity to reduce friction between body parts. Sexual health practitioners routinely recommend using personal lubricants during skin-to-skin contact to minimize friction, protect delicate tissue, and prevent discomfort.
Related advice on clitoral care
The advice follows previous recommendations from sexologist Angelina Prytkova, who addressed women on the topic of proper clitoral hygiene and care. Prytkova urged women as a primary step to discard the famous vacuum stimulator sex toy known as the penguin.
The clitoris is a complex anatomical structure containing thousands of sensory nerve endings dedicated to female sexual pleasure. Vacuum stimulators, which use touchless air pressure pulsators to gently stimulate the clitoral glans, grew into major commercial successes within the global sexual wellness industry.
However, sexual health professionals frequently caution that relying heavily or exclusively on high-intensity stimulation devices can desensitize delicate nerve endings, leading experts to recommend varied techniques and manual stimulation methods for long-term satisfaction.
