Do orgasmic experiences pose a danger in attracting spirit attachments or perhaps do the opposite by enhancing connection to Creator’s energy because of its joyous nature?

Your question, as often is the case, is finally crafted because it contains the answer within. The orgasmic experience is a joyous one and very akin to the energy of Creator’s love, and the experience of being in Creator’s love beam more directly than human can experience is very much a joyous and even ecstatic experience. So this raises the vibration rather than lowers, and will not incur any hazard but will do the opposite. There will be a strengthening of defenses unless the intention for the pleasure has a lowly purpose through subjugation of the partner or a focusing on dark doings in some fashion. This is what is meant by the word perversion, the re-channeling of what otherwise would be an exalted undertaking to warp its intentions, and often the target, to a dark purpose in some way with a dark meaning. And while the nervous responses may be rewarding in and of themselves, there will not be a divine participation or a raising of vibration to make the person more in alignment spiritually. That will only happen when love is the intention.
