Having sex and sneaky links

I just admire a lot how people can have sneaky links and enjoy their sexuality in general. I just can’t do that. I already lost my virginity with an ex boyfriend 2 years ago but I haven’t have sex with any other guy and is because I feel I can’t do it if I don’t have trust and an emotional connection with this person.

I feel frustrated because I do want to have sex again and I have the chance to do it with someone I know, but I just feel that in the moment I’m not going to want to do it, even tho I do want.

I also feel that is because I don’t know what to do I don’t know how to move how to act etc so is like I feel is diferente because if is a sneaky link you have to reach certain expectations

Do I have to wait for a new bf to start enjoying my sexuality again?
