I answered you on the italian forum, but I think that reply could be useful to many in the same situation of yours.
I have a problem with love and sex, I feel that most people are not compatible with me
If you feel like you have a problem in this area, start by stopping exalting it with this problem-possession thing. Stop with "I have" a problem. You can also say there is a problem, it's realistic-something like that really exists. But when did you take possession of it? Did you acquire the problem and now it is yours? Is your name engraved over the problem?
The problem is there, but since it is not yours, just remove it. Don't "keep" something that simply sits there without belonging to you. Nothing will be more yours than what you decide to take possession of. Is happiness yours because it is there in your life or because you wanted to get it? Is the problem yours because it is there or because you made sure to finally get it? No, it just sits there. That does not make it yours.
my parents are very strict and do not want to accept my homosexuality
With all due respect to your parents, it is not interesting what they think. Are they the ones who have to accept your homosexuality? Are they the ones who will have to share happy moments with your boyfriend? Do they have any say based on that? Do they have anything to do with your kissing with him? Will they be the ones who will be watching your romantic statements to evaluate them based on a personal score? There is no approval from them you tell me? But you know, there's no place in this world for their approval either, nobody needs that.
I feel a great frustration, anxiety and anguish that mix with sadness.
Sorry to be blunt, it's for your own good. You are not the only homosexual boy in history. There are homosexual boys like you. In fact, there are even bisexual guys who maybe even have same-sex preferences. You are not a circus freak case. In fact, I'll tell you even further. In nature itself certain animals have same-sex relationships. You are not a unique case even if we think of everything else that is endowed with sentient life. Now, you are an evolved human being: so there are those who are compatible with you.
You are more experienced than me in astrology (and you know it), you know how astrology works, etc. You know how some karmic issues work. It is not a mystery to you. You know that's the reality and "no, nobody's compatible with it" is not the reality, it's just a problem you've built up that grips your mind. However, since your magical power is programmed by your mind, you have to solve this (I would try hypnosis). Otherwise you can do even the Klim ×49 vibration for 360 million days and not really achieve so much.
I feel that I am healing emotionally because the meditation with the Wunjo rune is working.
Also the healing of the emotional body. I think it's even more necessary. From the High Priestess Lady Lydia.
I have seen with Astrology that I will be able to have an intense and passionate relationship, but I do not know how to make it manifest in practice
I recommend using the Jera Rune in such cases. But that's what I would do.
even when it will happen exactly, I only know that it can happen
That's right. You have to live your life with your own power. You must not assist others as they try to live their lives with their spiritual degradation. You understand.
I think that no one can love me as I desire
Do you think because it is so? Or do you only worry about this eventuality? Is an eventuality very likely in itself or only based on our concern? If you feel cold you will feel it more or less intensely based on your tolerance, your psychological state, what you think. But take a thermometer, will you change the temperature value in degrees based on how you hope? Yes, you think that way, but when is something in your head and when is it also outside? Have you seen this thing outside your head? Have you observed the rest of your life? Even if you had, you know that the future is not etched on the rock, so what exactly is outside of you that is also inside?
and for what I long for from the deep of my heart.
You crave your desires and nothing more than your desires you crave. So free yourself from what is in your path to distract you from what you crave. You crave one thing, there is only you looking at your desire. Where is the rest? Just you and this thing. The road will be so long depending on your power, your mental condition and the state of your karma. But you are there. You are here and the thing is there. And there is the road. There is really nothing else, but no less than these things.
Meditation for emotional healing is helping me.
If you see progress, how much sense does it make to persist in doubting? You see results, you still yearn for them. Because you already crave them.
What do you want to do?
Your own good.
Others will be well not in living in your place, but living by themselves. Yours is not selfishness. It is the good of all who understand it and all who do not. I bring you an example: your future beloved, do you think he deserves not to be happy with you because your parents do not approve of your homosexuality? So do you think it is more altruistic of you to not only make him suffer, but not even let him get to know you? Or do you still think this is good for your parents? Do you think they are okay with living someone else's life because it takes away their time to focus on their own? Where is the selflessness? Where are the selfish gestures?
