I’ve never been able to get sex :(

I’ve been like permanently horny since I was 18. I like guys and I’m friendly and told I’m pretty but they never flirt with me or see me sexually. I find that really hard when my friends are talking about all their sexcapades and at 28 I’ve never even managed to have a kiss or sex. It’s really worrying me now, I think about sex near constantly. Im a flirt too, eurgh I just wanna sleep with someone . It makes me worry that men just see me as non sexual
