Better question, do you think an alien would have sex with you?
Considering you live in a world where dolphins use fishes to masturbate and human zoophilia etc. is a thing, it's possible. Sentient beings could be naturally kinky for all we know, since that's such a strong venue of socialization and brain development.
Of course, a lot of people get this idea aliens are realistic only if they look like starfishes drawn by someone high on LSD. Most biologists now agree it's unlikely aliens would have dramatically different body plans from the myriad species who've evolved on Earth. You might argue not every life-capable world would be Earthlike, but as I mentioned before, body temperature compatibility would be a must for obvious reasons.
Or maybe I'm overthinking this and that was merely a joke adressed at the fact a lot gamers online are in reality scrawny, unattractive beta males...
