I don't know if it's lack of sincerity of purpose, or that you think your parents or siblings are not expecting you to have a boyfriend or girlfriend at your adult age, that's why some of you date in the shadows.
If you cannot introduce your man or woman to your one sibling
at least, within few months of dating, then you're not helping yourself.
Especially if you're above 23.
Your parents will not tell you to go and have sex, or date someone.
But they would be asking you why are you not bringing anyone to them, wheh they begin to sense that
time is of the essence for you.
You cannot blame your parents for that.
They don't follow you everywhere, & they expect that the good upbringing that they have given to you, should be your guide in making key decisions concerning your life.
