Apologies for the ? in the title

So I learned about kegels and its benefits and tried to do the exercises. The internet says to contract and hold the muscle for 10 sec and then release.

I found out the muscle but i realize i am not able to contract it for more than 2 secs. It just falls back. If i do manage for some time i feel like i am contracting muscles of my butt, my ahole and my lower tummy.

Am i doing the exercise correctly or i am focusing on the wrong muscles ? Did anyone else have problems contracting the muscle for 10 secs ?
