Tell your love to your crush!
Okay many has problem on this because their crush might be around their college, working place, neighbourhood and etc. Most of the worries are because what the other party will respond. This is worst scenario for LGBT as well. Actually, love is universal.
To gain an answer, you must ask a question first! Giving a hint might make your life difficult, you can't control the misunderstanding. Publish on the social media is worst as almost everyone around you, will think you are talking about them.
The only way is tell it and receive the answer. You might be rejected but its their right. You can find a better one you see or vice versa which promises happy ending.
Don't rush yourself, talk to the person you like. Get to know them, be casual and finally go with this proposing thing. The most important thing is don't be desperate or psycho. You might freak them out. Okay, actually human made this proposing thing very difficult. It looks like an event or party. The worst is when you have been rejected, the whole world knows. So don't messed up with studpidity. Just sit with him or her on a cafe and silently say you like her! Give her some time to respond pls. That's it, magic will start after that.
Girls stop the glass ceiling stating that only male can propose. Come on! You have full rights to say out your feeling. Just find the right way and time!
Goodluck!
