True Love is not just a sexual relationship. In fact, someone who is truly in love is most likely willing to never, or very rarely, have sex with their partner. Of course, people who are truly in love may want to have sex with each other (sometimes more often than not). Lovers respect each other, so if one does not want sex, the other will accept that. If you need sex in a relationship, then you are not truly in love. Deep love is a state of mind, spirit, and body. Someone who is truly in love can use their mind and spirit to control the urges of their hormone driven body.
In fact, true love can be divide into three categories:
The first is friendship/sibling love. Friendship is a type of deep love that is not sexual or even romantic; however I am aware that "Friend's with Benefits" maybe an exception to this. You are there for them as much as they are there for you. You care about each other and support each other. You can feel betrayed at times, but you can also forgive. Friendships, like partnerships, can end.
The second is a Partnership. This love can be sexual and/or romantic. It's when you have a husband, a boy/girlfriend, and/or a romantic party (a group of three or more lovers who are in an agreement to be together and know of each other). Sex and romance is not needed, but most the time it is there. You support and care for each other.
The third is parental/maternal love. It is the love that a parent has for their child. Sadly, not all parents have this love for their children, but for those that do, it is a deep never-ending love.
In a way, A Wiccan's Coven can fall into all the categories. As a Wiccan, I understand that this maybe classified as a fourth love, but I am placing under these three love categories. It is a family type love with the members acting according to each love and differently from one another.
Merrry part and blessed be, Dear Seeker. I may create a part 3 later.
