Practice
Frottage.
Sexual contact through clothing or skin-on-skin without penetration, typically genital or groin contact between partners. Often used in queer-male contexts as a low-risk activity (no fluid exchange, low STI transmission risk per BASHH guidance) and in mixed-orientation early-relationship contexts. Distinct from grinding (which can include non-genital contact like leg-on-leg) and from non-consensual frotteurism (the criminal practice).
