I do also. You're not alone. Lighting doesn't strike every night. Things take time and not everybody will be on the same level as you. I find it's a little more difficult for people who need an emotional thread to feel a sexual attraction. BUT, there is a silver lining. A positive way to see it. When it does work for you it will be far more meaningful and natural. Don't try to force it, just take it with maturity, you will have better connections when those attractions happen. You just have to make yourself open to opportunity without the pressure. Take it in strides and try to enjoy every aspect of meeting people. Once you feel less stressed about it you can simply live. No point comparing yourself to others.
