Doesn't sound like fun

Sex and the antiarch:
The first act of copulation has been traced back to ancient animals that were endowed with such cumbersome sexual organs they had to mate side by side.
Fossilised features of antiarch fish suggest that early intercourse was not the smoothest of affairs, with males faced with the task of steering their bony L-shaped organs between twin genital plates that adorned the females like tiny cheese graters.

No mention of love or kisses,  Nor is it surprising that the practice fell into disuse:
The discovery of such ancient copulation means that sex with internal fertilisation evolved early on in the history of vertebrates but was then lost, with fish reverting back to spawning in water, and then evolved again in a different way.
