Yes, you are right about your insights concerning your SR chart this year.
The Sun /Venus in the 7th and Venus trine Pluto opposing Asc. all point to opportunities for romantic relationships.
But opportunities are just that---potential relationships.
So we need to go back to your natal to see what you need to do to take advantage of your relationship potential that opportunities will bring to you.
I see three important areas of possible concern, which you should be aware of, in future romantic interactions.
Your Ascendant is the first impression that you make. Neptune/Uranus right there, in your 1st, hovering near the Ascendant have positive and negative influence. They are very nicely aspected, which is great. Especially the trine to Venus in Taurus.
But Neptune/Uranus in the first can send mixed messages to people whom you interact with socially. You may seem Neptunian, compassionate, emotionally connected with them and sensitive. But the Uranus is a very different energy. And you may also send out a cold, distant, disengaged vibe.
Uranus/Neptune in the 1st can present itself like a sweet, nerdy, goof, somewhat erratic, whom is harmless, but not to be taken seriously by others.
So it will be important for you to master the highest energy of that 1st house conjunction, so potential partners will see the dynamic powerful energy behind it, like the sextile to Saturn and Pluto and the trine to Venus. Those aspects promise loyalty, stability and depth of passion.
Allow people to see and feel your Venus in Taurus energy: your love, appreciation, gentle nature, talents and skills, nurturing energy. Your caring nature and earthy fun.
That Venus energy can be overwhelmed by all of your Air, which gets you stuck in your head, and anxiety can take over quickly. Sun/Mercury and Moon in 5th in Gemini can trigger nervousness and anxiety when faced with 'love' potential or dating situations. You may question everything and anything and get in your own way.
The square to Saturn from your Moon is an aspect to really study. Read as much as you can about it. get to the heart of it so you can rise above the most bothersome aspects of it. Luckily the Saturn has some very nice mitigating aspects which can elevate the energy.
SAturn sextiles Neptune/Ascendant and trines Pluto. So when in doubt, share your metaphysical knowledge with others. Show them your cosmic wisdom and your ability to transcend earthly flaws.
In discussing relationships, we have to look at your T-Square to Mars in Virgo in the 8th.

Having Mars in the 8th is a very good thing. But the squares to it can be difficult sometimes. Again, read and study as much as possible about Mars in Virgo and T-squares to Mars in the 8th. There are positive sides to it but also difficulties. And the mars in the 8th is the key to successful relationships.
Mars in Virgo in the 8th, being squared by the Sun and Jupiter/Pluto can be reigned in by you if need be. If you allow yourself free reign, you may say a lot of things you will regret. Mars in Virgo can be insecure and may strike out at others defensively. They can be very funny and quick-witted, but it hurts others and works against you if not controlled.
You mentioned the SR Venus being opposed your Asc, and wondered if your style of dress, etc, might put others off.
If that came to mind for you, then YES, by all means, make a change. Ask a woman friend that you trust to help you. Buy a few new wardrobe pieces, change your hair, work on your walk or your posture? This is an opportunity cycle for you and you need to make the best of it.
A Solar Return can bring you opportunity, but it still is up to you to make the changes and the progress needed to take advantage of the circumstances.
In summary, you may need to work on your 1st impression, and you're delivery.
Sincerely discuss it with friends. What do they think of 'you' in social situations. How do they see you, and do they have any suggestions?
I wouldn't want your emphasis of Gemini energy to overpower the stability of loyal, grounded Earth, which lies just below the surface. We want potential partners to see that you have a solid, stable consistent emotional foundation and it might be up to you to learn how to convey that.
