Always people treated the love magic carefully, even with caution, sort of like a love spell or prying it against free will, it means evil, and evil is punishable. Most love spells work just like that. In our case everything is completely different. Each ritual depends on the visualization enclosed in it and if you do not wish evil on to a partner, but only genuinely love and want to share happiness and prosperity, then there is nothing to punish you for.
More powerful rituals are against betrayals and the generosity of the partner. This is the most interesting part of red magic, the most energy-consuming. BUT why be the Magician if you can not receive desirable? Go ahead and get everything you want.
