There are as wide a range of fetishes as there are people. A fetish can be defined as a sexual arousal from a situation or object, such as feet, humiliation, or watersports. It could also be defined as a sexual desire linked to something abnormal. The most common fetish is a foot fetish, though there are plenty of others. Having a fetish does not make you weird - it means you have specific tastes that others may not have. However, there are plenty out there who will share your fetish, and you will find a partner not only accepting of your fetish, but willing to fulfill your desire you with.
The first thing to do is discuss your fetish with your partner. They will want to know the specifics of your fetish to make sure they get it right. For example, if you enjoy a foot fetish, your partner may want to know whether to keep stocking and heels in for as long as possible, or where you'd like to finish (such as on their foot with a footjob). If you find the idea of being urinated on appealing, then your partner will need time to drink enough liquids to make sure they can deliver.
When it comes to taking part in your fetish, make sure the location is appropriate for what you want to do. If you are interested in a caning then the location may not be as important as someone seeking hardsports, where a bathroom or wet room is more suitable to ensure a good clean-up. For those going to the partner's place, make sure you give them plenty of time to get everything ready. After all, you want a good time, not a rushed time.
The most important thing to remember is to have fun and communicate with your partner. If they are doing something with your chosen fetish that you are really enjoying, let them know. Just because it is seen as taboo doesn't mean you can't enjoy it.
