The Swamp Thing would be inclined to agree, though he may be too much the gentleman to give the details. A nature spirit with the memories of a man, the Swamp Thing inhabits plant life, stimulating its growth until he fashions a man-like body. But, well, only so man-like. He assumed a relationship with a human woman would be beyond him, that any feelings he developed for anyone who crossed his path would never be returned.
As joyous as this made the Swamp Thing (“Alec” to her), he almost immediately worried about fulfilling her physical needs. Their solution was as unconventional as interspecies dating: he fashioned a yam-like food from his body. After eating it, Abby shared a little of his consciousness, and the two began to frolic. Abby narrated the next few moments, and her usual bright but unschooled dialogue (“Everything’s alive, and it’s all made from the same stuff! I never realized…”) gave way to poetic expression more typical of “Alec.” Meanwhile, the art goes positively psychedelic. Alan Moore’s Swamp Thing prose could fill a small book of its own, but here’s a brief sample:
Spring came, and everything in the world woke up… My hand shatters the pool, a hundred glass beads exploding out between my fingers. A brief anti-gravity necklace settles against my throat, collapsing, dissolving, warm as it melts away…
Looking up through his eyes: the pale woman glances down, a burning flower adrift on the milk waterfall of her hair. Its lank tips draw clear sable brushstrokes between the lichens engraving my chest. She is… so beautiful… I… …am… …so… …beautiful… A tide of emeralds engulfs me. I’m falling into him. I don’t care.
Such psychic communion is a metaphor for sex at its best, or at least its most powerful. “Alec” and Abby’s union would eventually draw fire from (fictional) sexual conservatives (and probably real ones, too), but few of the series’ fans would deny their love was pure. In X-Men, Cyclops’ liaison with Emma Frost stepped into muddier moral territory.
Constantly assuring the married Cyclops that thoughts are “just thoughts,” Emma simply thinks of herself clothed as his wife Jean, in the days when Jean’s own psychic powers had filled her with madness, evil… and passion. And then she lets Cyclops “share the thought.” Here, psychic sex also feels like cybersex, the kind that cheaters may justify as “just texting.”

 Tough to trace this one, as her feelings evolved slowly over the years, but she always treated him kindly.
