You will get many opinions on this. Some say speaking in tongues is necessary for Christians. Various Pentecostal denominations might say that. Others say it's of the devil. Baptists tend to say that. I suggest a cautious middle way. That there is something valid to it but also that there are counterfeits. I think avoiding the counterfeits is important, as is any sort of 'training' in speaking in tongues. It should never be something you can turn on like water from a faucet. It is, when genuine, the Holy Spirit breaking through our thick skulls to bring us into prayer. It is not something Elmer Gantry would know a thing about.
The modern origins of the charismatic movement started in response to the terrifying vision of pope Leo XIII, who called for prayers for an outpouring of the Holy Spirit at the dawn of the 20th century. But the Holy Spirit has never been fully out of commission in the long history of the Catholic Church. So we can accept speaking in tongues as normal, as Catholic, as good. But carefully avoiding the craziness that some Protestants are in to like 'holy laughter' which makes no sense at all.
If you are speaking in tongues, do not neglect the other more standard aspects of your spiritual growth. Standardized prayers and mental prayer, confession and spiritual direction, Bible reading and spiritual reading, the Liturgy of the Hours, Mass (even daily) when it's available, all of that. Be thankful for what you have been given, particularly if it is accompanied by tears. Anybody can make noises. Anybody can do weird and undignified things. Avoid that. But if the Holy Spirit hits you on the head with prayer in tongues, then humbly go with it. For a while, until the next time. Avoiding counterfeits, which are out there.
