When we have two verbs together in a sentence, the form of the second verb is influenced by the first verb.
This table shows which verbs require the second verb to take the -ing form.
|Verb + -ing|
|The gerund form (-ing) is used after certain verbs: avoid, admit, can't stand, deny, dislike, enjoy, hate, like, love, mind, practise.||

|The gerund form (-ing) is used after a verb + preposition: insist on, look forward to, etc.||
