How to initiate sex the best way?

Like how do you go from the kissing, to the foreplay, to the sex, etc?

Is there like a smoove online guide or some ****?

I feel like my motivation for sex has declined a lot over the years and what used to come naturally now needs to be taught (SSRI use, being 29, etc).
