If you ask the question for personal reasons, is interacting sexually really the most relevant skill you are lacking? From what I read from you it seems like you don't have the ability to have a simple friendship with a woman. As long as you lack those skills any focus on sexuality is unlikely to yield much.

BTW, I find it interesting that over a decade ago, Eliezer described himself in a news story as a “volunteer virgin,” though he has since become sexually active.

In general drawing a lot of information out of such a statement in a news story is a bad idea. You have little idea about the context of the conversation between the journalist and Eliezer when Eliezer used the term “volunteer virgin”.

That implies he had opportunities for sexual relationships that he had simply declined until something happened to change his mind about pursuing them.

"Simply" is very likely wrong. Declining opportunities for sexual relationships is seldom simple and accepting them isn't either. Both are complicated.
