Let's talk about the difference between free love and free lust. Free lust is "fucking" anyone you want. Free love is treating each person as if you are in love with them up to their own point of comfort. One is all sex. The other says I just really love humans. Sex happens in free love, but because it's a form of expressing love and receiving it. If you talk about genitals specifically, you probably have the wrong idea
At the very start of the orgasm it is an individual primal lust. A desire that transcend beyond the bounds of love.Your body is taking what it needed to fulfill total release. You can love someone and sexually lust for them. My wife and I love each other, but we lust for each to maintain a healthy sex life. Maybe not free but we have sex for our “individual health.
Free lust defined. To have an intense desire, especially one that is sexual. This would be a hook up based on looks alone. Progressing to a sexual encounter where either or both partners expect to fulfill their desire without thinking of a future relationship (ie: a one night stand). Free love defined. To feel a deep romantic and sexual attachment to someone. That would be a hook up based on looks along with personality. Also progressing to a sexual encounter and moving towards a relationship. The free part means there is no attachment and the partners are "free" to have romantic relationships with whoever they wish.
I'm an older member, but experienced free love in the late 60's. Sex, Drugs, and Rock and Roll. any order.
