I'm not a teacher, just a student.
When I abstained for years from any kind of sexual relationships I found out I needed no one, as if my desire was gone, I started to see people differently, boys and girls, and had better friendships with all kinds of people.
Later, when I stopped being celibate, I found myself wanting a relationship, I wanted a girlfriend by my side and started to see girls with desire - I saw them for what they could be in my life, and felt the urge to have sex. So I guess normal people see with desire, people of the sex they are attracted to.
What I can say is that you can end that desire if you practice Buddhism. I know it might be hard but try to abstain from all sex. If you feel that urge, say no to that energy below - go for a walk, go to pee as that can give you urges, or search online for some techniques.
I say this because for you to practice tantric sex you need to know other more advanced techniques. So normal sex, even though it's ok to have it, it won't give you nirvana.
If you manage to practice celibacy you might find a friend, without the eyes of desire, and maybe who knows with time you might fall in love in love for him/her. And if you are a Buddhist, I would advise for you to be a part of a Buddhist sangha and to find a Buddhist practitioner you like.
You can ignore celibacy if you are not ready. But if you are, you will feel better in case you pull it off.
At the same time, there are many Buddhists out there who don't practice celibacy and want the same as you.
There is another question here from a similar nature:
How can I remove my desire for a relationship/ girlfriend?
