1. If someone irritates you when they first contact you, or you find something a bit odd, don't make the booking. Guaranteed they either won't turn up or, you will hate them.
2. Draw the line of professionalism and never ever cross it. Don't trust a client, and, be friendly but not friends. Don't ever make them believe you could be real life friends or lovers.
3. If possible, don't make yourself work if you don't feel like it, Take time out whenever you need it, and have another source of regular income so you aren't reliant on sex work.
