I think the cornsnakekid is right on this one. The lad's a bit confused. With some of these over-eager young gents, there's definitely an "any port in a storm" attitude. (Don't mean to get all nautical on y'all.)
The worst thing you can do is to clue him in to your disappointment. Tell him at least once per day (after 72hr. digestion period): "I'm proud of my gay snake!" If ladies of your own species are around, I'd skip the encouragement for that session.
In due time, your snake will either develop a fondness for the ladies, or write a best-selling memoir. Either way, it's win/win for you. :cheers:
