Are there perfective verbs that only accept perfective infinitives?

Question

The following perfective verbs are said to only accept perfective infinitives.

забыть - to forget
успеть - to manage, have time
удаться - to manage, succeed
суметь - to be able to manage
получиться - to succeed, manage

For example:

Я забыл купить марки. - I forgot to buy stamps.

Is that right that they only accept perfective infinitives as their dependencies? If yes, what is the logic behind that?

Answer 1

No, the imperfect form of the verb can also be used if we show the time period:

• Я все время забывал покупать марки.
• Я никогда не успевал приходить вовремя.

Thus, we mean a repetitive action. But if there was one action (I did it and that's all), then the perfect form of the verb is obligatory.
