There is no set of toys you are supposed to want because you are with a woman. What matters is what each of you enjoys - external touch, penetration, shared play, something hands-free, or something else entirely. Toys fit into that easily, as tools among tools.
So this is less a special category than a well-stocked shelf. Here is what tends to earn its place, and why.
Clitoral toys, usually the place to start
For many couples, clitoral toys end up as the core of the collection. A suction or air-pulse toy gives a deep, specific sensation that hands and mouths complement rather than compete with, and it frees you to focus attention elsewhere. Small, precise bullet vibrators are the versatile everyday option - easy to bring into almost anything you are already doing. Both add a register that is hard to produce any other way.
Wearable and hands-free toys
Toys that stay in place without being held open up the most possibilities for two people. A wearable clitoral toy can be worn during other activity, and many are remote-controlled, which puts the pace in a partner's hands - a small shift that a lot of couples find genuinely charged. The point is less the technology than what it frees your hands and attention to do.
Dildos, harnesses and strap-ons
For penetration, a dildo used by hand or worn in a harness is the flexible core. A strap-on kit lets one partner penetrate the other hands-free, which changes the dynamic and the angles available, and a decent adjustable harness fits a range of bodies comfortably. Choose body-safe silicone, start with a moderate size, and look for a harness that takes different dildos so the kit grows with you rather than locking you into one piece. Some strap-ons include a portion that stimulates the wearer too, so the penetrating partner is not left out.
Double-ended and shared toys
Double-ended dildos allow simultaneous penetration and are a genuine favourite for some, though they take a little coordination and are not the easiest starting point. If you share any toy between bodies, hygiene is the one firm rule: wash it between uses and use a new condom for each partner - and change the condom when moving between anal and vaginal use too. That small step aside, sharing is part of the fun.
Materials and lube, briefly
The universals apply. Body-safe, non-porous materials - silicone, glass, steel. A good water-based lubricant, which is safe with silicone toys where silicone lube is not. Clean everything properly, especially anything shared. None of this is specific to any couple; it is simply how you keep good toys good.
The short version
There is no set way sex between women goes, and toys are only ever an option, not a requirement. A clitoral or suction toy, a versatile bullet, a dildo with an adjustable harness, and body-safe materials with plenty of water-based lube will cover most of what you would want to start with. Share safely, choose on feel, and build the collection around what you actually enjoy rather than what a category tells you to.
There is no starter set you are supposed to want - only the one that suits the two of you.
