Some verbs can only be followed by a gerund and some verbs can only be followed by an infinitive:
We avoided using the motorways. 
We avoided to use the motorways. 
I want to go home early. I want going home early.
There are some guidelines that might help us decide whether to use a gerund or infinitive. For example:
1. Gerunds often perform exactly the same function as a noun:
This job involves dealing with customers.
This job involves contact with customers.
We delayed launching the product until January.
We delayed the launch until January.
2. We often use infinitives for actions that happen after the action of the main verb:
He decided to work at the weekend. [The decision was before the work.]
We expect to have the results next week. [The expectation is before obtaining the results.]
However, there are no definitive 'rules' without exceptions so we have to learn which to use.
Here are some examples:

Note that 'to' in these expressions is a preposition. It is not part of an infinitive and that is why we see 'to shopping' etc.
They're committed to finding a solution. They're committed to find a solution.
'Before' and 'after'
Whether we are talking about the past, present or future, 'before' and 'after' can be followed by the gerund as an alternative to a subject and verb:
I always check the electrics before giving a presentation. ['I give']
After speaking to him yesterday, I decided to cancel the order. ['I spoke']
Before leaving this afternoon, could you call Tom for me? ['you leave']
Suggest
We never use the infinitive with 'suggest' - with or without an object:
I suggest to have a presentation. I suggest you to have a presentation.
If it is necessary to use an object in order to specify 'who' the suggestion was made to, we use 'to'.
These are the correct ways to use this verb:
+ noun or gerund | + object + bare infinitive |
I suggest a presentation. I suggest having a presentation. I suggested a presentation (to Thomas/him). |
I suggest (that) we have a presentation.
I suggest (that) you go to the presentation.
I suggested (to Thomas/him that) we have a presentation.
