Do you think I have more freedom being single?

There are advantages and disadvantages in both cases. If you are single one advantage is you are free to see whoever you like and for as long as you like. Not being single can at times give you stability of having a person that you can rely on and be there whenever you need them.

Totally I enjoy being single too even though I'm a still having regular sex

Yep. Same reason that I like being single too.

absolutely

I believe you can have freedom when you are in a relationship also.
Nothing is better than having someone by your side who accepts everything about you.
I call that being free. 🙂

Well you can date who you want I guess, and have no strings attached arrangements, but I personally prefer a loving relationship. Sadly I'm not in one.
