If there's one thing wizards are good at, it's making sure that no matter what the other species is they can -ahem- do it. With magic and gods -ahem- explicitly in the picture the chance of the answer to MC's last question being "no" or even "it's difficult" are truly minuscule. I would complain that it's not fair to expose members of a pre-Information Age society to material designed and polished with modern marketing techniques to appeal to and persuade a far more jaded audience, but it's for space travel and to (lets be honest) a person pretty much chosen both in and out of character to be the most receptive and suitable subject, so I'll allow it 
(Come on, a "mere merchant" who is a self-exiled foreign princess already bit by the travel bug and falling notably into MC's strike zone as an attractive mate is NOT just a coincidence, especially when the god of travel and commerce is specifically who arranged for the time and place of his arrival.)
Without going into too much detail on biology, I will note that a snake's tail is actually very short in most species, so depending on just how the two sets of physiology were smooshed together by whatever god or wizard decided to have half-snake people MC may be lookin' for luv in the wrong places, or or may have his fascinated stare at the cute little flicks as she talks about something drastically misunderstood
Or for that matter, she might despair at how he doesn't even notice the cute little flicks she tries to attract his interest with, steadfastly keeping a neutral eye on her boring old abdomen and lower back, not even the part where her scales have the most intricate pattern!
That said, she is very cute, and the descriptions of how her body language is different are worth a note on their own, do try to keep that up as the cast inevitably grows. With twenty feet of length she should be able to loom quite effectively when she wants to, for one thing, and possibly even when she doesn't mean to but feels threatened or outraged. For another, though her coloration is more in line with a venomous snake than a constrictor as such, she may still be a little too good at hugs for the well being of anyone with less extreme variations from the human standard...
