Not necessary, no 
I'm considering only cases in which the subjects are different (if not, we use "de + infinitive clause")
- There are some verbs that are always followed by a subjunctive: (this list is not exhaustive...
)
avoir peur --- to fear
douter --- to doubt
aimer --- to like
vouloir/avoir envie --- to want
préférer --- to prefer
souhaiter --- to wish
attendre --- to wait/to expect
falloir --- to need/must
refuse --- to refuse
- some prepositions are always followed by a subjunctive whenever they are followed by a clause (that's why there is "que", it's like "that")
bien que = although
jusqu'à ce que = until
pour que = in order to, to
avant que = before
- some verbs are followed by a subjunctive only if the main sentence has a negation: penser (to think), croire (to believe), comprendre (to understand)... It can be explain because subjunctive is usually found in a clause that is associated with a condition, a wish, something that is uncertain or that hasn't happened yet/won't happen/hadn't happened in the past. Some examples:
Je pense qu'il est déjà midi (est ---> indicative) --- I think that it's already noon = I'm 80% sure that it's noon or past noon
Je ne pense pas qu'il soit déjà midi (soit ---> subjunctive) --- I don't think that it's already noon = I'm 20% sure that it's noon or past noon
Je pense qu'il n'est pas encore midi (est ---> indicative) --- I think that it's not noon yet = I'm 80% sure that it's not noon >>> What matters is what's inside the clause (= after "que"). If it's almost certain, it will be indicative. If it's probably not happening, it will be a subjunctive. One last example?
Je ne pense pas qu'il ne soit pas midi (soit ---> subj.) --- I don't think that it's not noon. The clause says : it's not noon. And I'm like 20% sure that it's not true (je
ne pense
pas que...) ---> it's uncertain ---> subjunctive.
I know that it's really not easy to deal with and I hope I'm not making things more complicated than they really are... sooooo: N'hésite pas à me demander quand tu n'es pas sûre
