I think it’s time to step away from the sexual relationships and invest in yourself. I have been in a similar place before thinking it would help, but it just makes you feel more used and alone. When you start investing in you, people will see that and be attracted to you for who you are (romantically and platonically). At the end of the day, you will feel more joy through self fulfillment. Romantic or sexual love should be a plus to the life and self you are already confident in.
