You can buy a bra cheap at a thrift store–just pretend you are shopping for your girlfriend or for a costume party. You can order something online that is like a fabric bracelet that clasps around your wrist using the exact eyelet and hooks you would find on a bra. You can use this to practice unhooking the bracelet with your free hand. If you’re a girl then it’s a little easier and you can practice with your own bra.

Some front-fastening bras have one large hook that slides down into a loop of fabric, rather than side to side or forward and back, like with the hook and eyelet.

You may want to start by just hooking and unhooking the bra when it is loose and there is no tension in the strap so you can get the feel for how the eyelets hook and unhook. Practice using first one hand, then the other, to see which one feels better. It may not necessarily be your dominant hand.

Now would be a good time to confirm that she wants you to proceed. When your hand is on the clasp, simply pause and ask her, “Is this okay?” Don’t disrespect your partner by assuming she’s okay with you taking off her bra. If she says no, stop what you’re doing and go back to making out. Make sure your hand is warm before you slide it under her shirt. It could be an unpleasant shock to place a cold hand on her warm skin.

Though it’s probably obvious what you’re doing, make sure she’s okay with what you are about to do. It doesn’t have to be a big deal and can even be kind of sexy. Just pause and whisper “Is this okay?” If she tells you yes then you can proceed. If she says no, don’t try to force anything. Just remove your hand and enjoy kissing her.

The hook is not always on the same side, so if this doesn’t work, try pressing your thumb against your middle finger and pulling up while your index finger pulls down.
