Lots would sleep with you. You can slide into a conversation by mentioning your YouTube channel.
Find someone who likes sci-fi like you do. I am sure there are groups of people on sites who discuss sci-fi and the like.
Find someone you have something in common with. That's the first step. Then you can build a friendship easily, because you have something to talk about. Then, things can lead elsewhere from that point.
Use humor. Make slight innuendo. Introduce it slowly. Be humorous from I'd say the second date on. You don't want to seem like a clown, but let her know you can be funny. After the 4th or 5th date, use your humor to introduce the innuendo. Saying something like, "I'd let you board my Enterprise" would be funny, and get your point across at the same time.
