Not comfortable with fetishes? There's nothing wrong with you.

For some people sexy lingerie, high heels, dressing up and other fetishes cause the feeling of playing a role or an impression of artificiality.
Others are upset because they would like their partner to want it without using any artifice.
For another group of people, fetishes are just valid games to spice up the relationship.
Each person feels differently and everything is fine. Not enjoying a fetish does not mean that you are sexually repressed.
The opposite is also true. Liking a fetish does not necessarily mean that a person is sexually free. Even some people are dependent on it for pleasure. Without a sexual fantasy stimulus, some people are unable to enjoy themselves and this is not very healthy.
It is recommended to be open to experiment and have new experiences. So you will know yourself and know what you like. You can even discover new pleasures.
However, it is important to know that you can also have a more naturalistic view of sex and simply dislike fetishes.
I suggest you do it and enjoy it if that's your wish. And that it doesn't make one realize that it's just to be "the well resolved" or the "liberal". Don't just do it to please someone else.
Sexual freedom is also saying no to what you don't want.
