I tell you.
You must know that being effeminate or 'less masculine'(average masculinity) is nothing bad. Nothing is set in stone.
So please, don't get mad or sad if I describe your body. I don't think any of these physical traits are bad. So should you.
You have thin chest and arms, you're not very muscular. But you are thicker around your waist and legs. Women usually have this complexion. In the case of women that fat is for pregnancy. You maybe needed for nutrient storage reasons or not. I don't know.
Second, you don't have a very agressive or tough/serious face. You have a more calm, peaceful one. That is also an effeminate trait (note that being feminine, effeminate is not something wrong, and shouldn't be consider that way)
So yes, you're 'effeminate'. Or just effeminate, who cares...
