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 does not seem like a normal activity but if it does not affect anyone I see no harm in partaking in this activity.

Should I feel guilty about my behavior?
user
It is not for me to decide where or not you should feel guilty. In general a person may feel guilty when they feel they have broken their own moral character. Something they regret and feel responsible for. So you first may ask yourself if this behavior breaks one of your morals.

Like for instance you can ask yourself:
- if this behavior is harming anyone or yourself?
- Did I make an agreement with myself to not do it? And you like to keep your internal promises.

Guilt can also be a very useful emotion to improve yourself. But you should be careful to not unnecessarily feel guilty.
