You can buy spermicide alone, yes, but it would probably be cheaper to buy a few condoms with nonoxynol-9 in the lubricant. The bitter taste I referred to in some condom lubrication is in fact this spermicide. My suggestion to you is that you ask a provider you trust if you could be the first appointment on a given day. Just be willing to schedule early and be flexible. If you ask for the first appointment of the day
today or tomorrow, it gives her more incentive to pretend that you are the first client when you actually are not.
