Transits involving Mars and/or Jupiter are associated with falling for someone. Transits involving Saturn suggest a readiness to commit (or a sudden imperative to commit, like it or not), so if you get Saturn transits with Mars and/or Jupiter at the same time, you're likely to be ready to start a relationship (if you're not already in one or otherwise occupied), and so you're primed to notice possible opportunities.
Saturn is opposing your Mars, and has been over the last half year. And squaring your Venus and Jupiter, too. And to top it off, Mercury, the ruler of your eighth house of sexuality, is currently stationing direct in opposition to your natal Saturn and within 2° orb square of your Jupiter. Plus, you're in your Saturn return period. You got your first direct pass a couple of months ago, then Saturn stationed retrograde conjunct your natal Saturn.
That t-square of yours is getting activated several times over. Looks like it's showing up in a positive way!
