Whenever we use two verbs together in English, the second verb must change to either an infinitive or gerund, or sometimes it can be either one. For example:
I enjoy have a coffee after dinner.
I enjoy to have a coffee after dinner.
I enjoy
having a coffee after dinner.
I need buy a dress.
I need buying a dress.
I need
to buy a dress.
I like go to the beach.
I like
to go to the beach.
OR
I like
going to the beach.
