I look at this chart and I see you, as the Sun, opposing Mars and squaring Jupiter and Pluto.
You say that you don't want a boyfriend but at the same time, you seem really concerned about what these casual flings think about you, and if they 'like' you.
That malefic T-square they you, the Sun are involved in, tells me that there are some conflicting feelings below the surface.
You are the Sun in Libra in the sign of romantic relationships, in the 3rd of local community.
So I think you might want to fall in love and have a solid relationship, deep down inside at least.
That Mars in Aries is opposing that dream or urge. IF you are having these physical flings, in the hopes that it will turn into something more, I am afraid it will not end up to your satisfaction. That Jupiter /Pluto square can describe 'social judgements' and feelings of being judged unfairly.
