Mutual Masturbation
Mutual masturbation is partners pleasuring each other's genitals by hand (or with toys) at the same time — or, in the other common sense, masturbating themselves side by side in each other's presence. Either way it's a shared, low-pressure act that blends solo-style pleasure with intimacy and watching. It's a complete experience on its own, a great warm-up, and one of the lower-risk sexual activities. It's also a way to learn exactly how a partner likes to be touched. It overlaps with handjobs, fingering, and voyeurism/exhibitionism.
The appeal is intimacy plus control — each person can guide or provide precisely the touch that works, while sharing the vulnerability and heat of pleasure together. Watching a partner touch themselves (or be touched) is its own turn-on, and it takes the pressure off 'performing.'
Partners face each other and use hands or toys on each other's genitals at once, or masturbate themselves while watching, often adding kissing, dirty talk, or guiding each other's technique. It can be leisurely or build to simultaneous orgasm.
One of the lowest-risk sex acts — no penetration means minimal STI risk, though fluids on hands moving between partners is worth a rinse. Keep nails trimmed, use lube, and enjoy.
