I've begun to think that I'm only attracted to a certain type of person that's almost unattainable, at least for me. First off, I'm almost freakishly tall for a girl and it's hard to find someone taller and muscular enough so that we look good together. I'm not into a certain type, so to speak, but I seem to like dark haired guys more often. I want someone who has a nice smile, is funny, attractive, educated, has the ability to teach me something new, has a balance of smoothness and silliness and someone I can share things with.
I don't feel attracted to really anyone anymore, and I'm starting to get scared that I'll just end up alone because my standards are too high? Below are some examples of guys I am into:

OR

OR

All of these men have strong jawlines and Tom Welling is muscular and either 6'3" or 6'4" - I forget. To me, that's swoon-worthy.
It's not just that I'm only attracted to these types of people, but I'm reduced to going on dating sites to find someone and the only people who are interested in me, look like this:

I don't know about you, but people like this make me uneasy.

It's stressful to know that I'm only attracted to people who will (most likely) never be attracted to me. The above three people are the ones I could think of off the top of my head that are attractive enough for my taste. To be quite honest, there has not been one person in a very long time that has piqued my interest. In all honesty, I wasn't attracted to my last boyfriend for the first month and a half of non-exclusive dating.

It feels horrible to not be attracted to anyone below "drop-dead gorgeous" appeal, but that's just how it is. I'm worried the guys I'm attracted to will never be attracted to me, and I'll end up having to settle for Child-Molester-Mustache-Man (as seen above) who is shorter than me (HUGE turn off, by the way - I just am not, nor have I ever been, attracted to someone who isn't at least 2 inches taller than me. I don't know how my standards got so high. I've always been broken up with, and I'm not known for having the best self-confidence so I'm at a loss for why I've stopped being attracted to anything less than a 9.5.

I know some people are going to say "You set your sights too high and you're going to end up alone" or "What a bitch" or some other condescending phrase. I already can hear it being shouted at me in my head, so don't waste your time voicing it.

I just don't know what to do....
