As I pointed out in my answer to "are earthworms our mothers?" these kind of questions often assume incorrect frame of reference. The reason we request Buddha (or our local teacher as Buddha's substitute) to continue teaching instead of entering parinirvana, is not because it can literally make Buddha (or teacher) change their mind and stay. The idea is to create a mental context in which A) the teacher feels motivated to continue teaching because he sees the teaching is in demand, B) the students stay aware of the fact that existence of the teaching in this world depends solely on Buddha and then generations of teachers passing it to one another, and now to the students, and C) the student clearly realizes that the teacher could very well leave this place but is instead making effort to stay and teach solely out of compassion for the students. When this context is established the teaching can happen effectively, because both the sides will engage actively and with no resistance.
Granted these are entry-level practices, but they are very important to establish as foundation. Otherwise what happens if you skip straight to advanced teaching, the student may get as arrogant as to metaphorically grab the teacher by the hair and swing around. Needless to say, it hurts the student first and foremost.

All Buddhas are masculine. No, it is not harmful to invite the Buddha. In fact, the Buddha mentioned several times that a person who has perfected Sathara Iddipada can live the maximum life span of a human at that time. It was about 120 years back then. So he could've stayed another 40 years had he been invited. Venerable Ananda had several opportunities to invite the Buddha. But it's said that Mara(the evil god) prevented him every time.

I'm not sure I understand your question(s) fully; however, since you seem to be coming from a Mahayana background, do remember that the Lotus Sutra reveals Buddha's entering parinirvana is merely an expedient device. He merely appears to enter parinirvana to "motivate" people, as it were. According to that Sutra, which claims to be the ultimate and true teaching of the Mahayana, the Buddha doesn't enter parinirvana but instead eternally abides in this world.
