How is love-making a spiritual experience? [nsfw]?

Or, from the opposite perspective, how is it not? How do you separate sex from love? If you believe they are inseparable, why do you think they are inseparable?

If possible, I hope you can talk about what specific physical experiences or practices bring up what kinds of spiritual connections or feelings for you. Is there any love-making practice that particularly connects you to your partner?

Even more, I’d like some insight into how you got to be this way. Were there experiences you had as a youth, or lessons you learned from some parent or other teacher that showed you sex either is or is not connected with love?
