Questions I have down below!

So when you have sex is there a ceartin hole that the penis has to be inserted in in order for it to be considered sex? If a guy fingers me can it break my hymen? If a guy rubs or puts his penis inside anywhere in my vagina, like for example near my clit would it be considered sex or does have to be in streets into a spefic hole for it to be considered sex? What is a orgasm and how do you know if you have had one? Please serious answers only! Thank you!
