Becky Crepsley-Fox links interest in the practice to sensation and control over pace, while advising partners to discuss comfort and boundaries.
Sexologist Becky Crepsley-Fox told the British newspaper Metro about an unusual sexual practice discussed on social media: some women use friction against a partner’s flexed biceps for stimulation. She said it may be pleasurable for some people, but it is not a universal way to reach orgasm.
Crepsley-Fox said some people find muscular arms attractive as a sign of masculinity, while pressure and movement can stimulate nerve endings. She also noted that a participant can control intensity and pace. These explanations reflect the specialist’s view and do not mean the practice will suit everyone.
The expert advises partners to discuss what feels comfortable and to take their time. In the interview, she suggested that the partner keep the arm steady while the woman communicates what movement and intensity work for her. Clothing can be left on to reduce friction; if there is direct skin contact, she advised using lubricant.
As with any sexual activity, mutual consent, comfort and the ability to stop at any time matter. The source also includes a separate reference to an earlier comment by another sexologist about clitoral care; it is not related to this practice and is not included here.
