Couples often indulge in the movements of intercourse (without penetration) to recreate some of the sensations and motions of intercourse. It is also known as 'outercourse.’ This may also involve fingering, frottage, erotic massage, footjob, mammary intercourse, or nipple stimulation.
Contrary to popular belief, non-penetrative sex can still include the risk of sexually-transmitted infections like herpes, genital warts, HPV, syphilis, or scabies.
