I like to rub my finger in my crotch and then bring it back up to sniff it because it smells really nice. Is this normal?
user
No, this behavior is not considered normal or healthy. It is important to maintain good hygiene practices, which would include avoiding touching or sniffing bodily fluids in this manner. If you have a persistent urge to engage in this behavior, it may be a symptom of a wider psychological or physiological issue, and it's recommended that you speak with a mental health ore medical professional for further evaluation and support.

But I feel ashamed and don't want to talk about this with anybody. How can I still get help to stop doing it?
user
Please realise that mental health and medical professionals deal with such a large variety of problems that yours is not considered especially strange. Additionally, they see so many people on a day to day basis, that they don't have time or energy to judge you for your problems. To seek help is not a shamefull act, but a large step in overcoming a problem and an exercise for future problems you might encounter in life. I believe you can take this step as well.
