I feel really lonely...?

So for a long time I've been really lonely. My friends have all had their boy stories to tell and I have nothing. I am a reasonably attractive girl but I have a very low self-esteem because I used to be ugly. (Ugly duckling syndrome) Anyway.. I feel like I'm dying inside. I'm not a homosexual because I'm really attracted to men so thats not the reason why I haven't found anyone. But im 21 years old and...TBH I just want to make out with someone already & even do more. I'm sexually frustrated as well. I dont know what to do. I dont know how to find people and the people I know I just cant date (even though I may like one) becuase they are all the exes of my friends.

I feel like ****, sometimes I cry in the shower or bed thinking about if someone was there with me. Its really depressing. I shut myself off to men and I do it subconsciously - but the only men I hang around I wouldn't date...so I'm now wanting to get drunk and do whatever. I wish someone would just knock on my door and ask me to coffee :(
