Being a cockslut is quite fun and rewarding, there's nothing like laying back and letting a man have his way with you. Course I'm a gal so maybe my opinion isn't what you wanted. Still getting it so there.
If you only get off being a slut, perhaps you should find a dominating woman. Course I'm going to call bullshit on not wanting to be a cockslut, considering it is how you reach orgasm. See there's this funny little thing called your mind, it is most of the enjoyment of sex. If you only get off one way, not wanting to do that is simply you being a complete fucking moron and listening to what others are saying on what you should enjoy.
I'll put it plainly, what you enjoy is your business. Who you do it with, is for the other person or persons to determine. Besides them, why care? The people who denounce anything are only saying I don't like it and want to push my views on everyone else. Doesn't work so don't listen, especially if it is a priest.
so you dont think ill be able to get rid of my sucking obsession? It feels weird that it turns me on even more when im called a slut and a whore while sucking
My experience is that these things come and go. Not real fast, but you might get sick and tired of this particular fetish, and move on to something else.
As far as feeling wierd about it, yeah. Those words carry a lot of negative connotation, no matter how hard we try to 'reclaim' them. And if someone you're doing this with is malicious, his negativity is going to come through his words. Find out who that person is and don't let them in your space again. We can be pretty vulnerable when we are sexually involved.
