I love someone but idk if he loves me back
You will never know until you take him into your mouth, complete the job, and swallow. At that moment, he will love you.
Try taking it slow and ease into it and then ask
Truth is, if he does you are lucky. If he does not, then he did not deserve you, and you'll definitely find someone else you find attractive.
You will never know until you ask.
Dont start off with LOVE, just ask if he would like to get together for coffee, lunch or a museum. The rest, good or bad will take care of itself.
