When I changed my name to Sex

When I worked at a car rental booking/reservation call centre I was very busy and the phone rang all the time with customers who wanted to book cars. I was also the person who had worked there the longest so my colleagues asked me questions between the calls. A lady asked me how she was going to access something in the computer. I replied F6 which is a key on the keyboard and with the next breath I answered the phone - Good morning this is car rental company X my name is Sex how can I help you? As soon as this word had left my tongue I though oh my God what shall I do now. I heard that the customer was wondering if he had heard my name correctly...I continued to talk as nothing had happened. To explain this for you guys who are not Swedish speaking the number six (6) is called sex in Sweden but sex is also called sex. So, that is why I mixed it up and because my name Siv is also very short and similar to the number sex/six. Really embarrassing!!!
