If you want a first toy: a bullet or a pressure wave vibrator. Both are small, easy to figure out and made for external use. Pick a bullet for simple vibration, or pressure wave for a stronger, no-contact sensation.
If you are new to kink: start with a collar or a beginner kit. A collar changes the mood with no learning curve, and a kit lets you try restraints, a blindfold and a gag before buying any of them on their own. Agree on a safeword before anything goes on.
If you want impact play: start soft, then go sharper. A suede or fluff flogger first, then a heart or acrylic paddle once you know how much sting you like. Stick to fleshy areas like the thighs and bottom.
If you are new to plugs: start small and go glass or silicone. A jeweled base looks the part, but the size of the plug is what matters. Every plug needs a flared base.
If you are buying a gift: a bondage bear, a pink vibrator or a boxed set. All three say it clearly without being too much. With word collars and paddles, pick a word you know they would choose for themselves.
If it is for content: holographic, rhinestone and patent. Shine reads on camera. Soft pastels photograph best in daylight or a ring light, not a dim bedroom.
On nipple clamps: keep the first session short. A few minutes is plenty. Blood rushing back when a clamp comes off is often more intense than putting it on, so take it off slowly.
On lube: water based with silicone toys. Silicone lube can damage silicone toys. A water based lube is safe with every toy in the edit, glass included.
