<human>: Can you succinctly summarize the text in 1-3 sentences?

I think something is wrong with me. I can't have flings with guys where it's just sex and nothing else. It feels strange. I just feel like there's something wrong with me because everyone else around me seems to be getting into these casual sex relationships and I'm just sitting here waiting until I have a boyfriend before I do anything. I'm just feeling a little unsure. The guy I just had a "booty-call" fling thing with just went home for the night and I don't feel in any way satisfied. I feel strange. I've never done this before. People call me "uptight" and a prude because I only sleep with guys I'm interested in pursuing a relationship with (or I've at least gone on a couple dates with). I feel uncomfortable because I feel like an outcast from the social norm. I want that sexual satisfaction, but I want it to be with someone I trust. I don't have to be married, but I at least want to have some sort of exclusivity with the other person. How do you guys and girls deal with this? I feel like there aren't any people around me my age that feel the same way I do, so it makes me feel isolated emotionally and sexually. I know I shouldn't feel like I've done something wrong, because I'm single and can do whatever I please with my body, but something inside of me just feels awkward about the whole situation. Anyways, I just wanted to reach out to see if anyone else has this sort of issue, or if anyone had any insight into how I'm feeling.
<bot>: Can't have flings or one night stands purely for sexual gain without feeling awkward and unsatisfied. Is something wrong with me because I can't understand or follow a modern social convention? Being called uptight, a prude etc.
