I Find Myself Repressing My Desire to be Sexual Because It's Not Proper

Hi Betty,
I'm 34 and have always had a healthy sex drive. I have had anonymous sex and I love it. I find myself repressing my desire to be sexual, because it's not "proper". I don't have sex regularly, because I do not have a partner. So, that leaves me quite frustrated.
I want to give myself permission to have protected sex with as many men as I like, because I simply like sex. How do I move past the social norms and finally embrace who I am.
Dear S,
