I met a guy about 3wks ago, he told me he has been single for 3m and he has a booty call. Should these be red flag to worry about or is worth getting to know.

Is he looking for another booty call? I wouldn't waste my time.

He said he wants something serious

See how he reacts to No Booty. If you want to, keep your clothes on for a few months to see if he's still around. By then he might be worth some emotional investment.

With what you said there is no idea if he is or is not, It appears he is honest, but then a man telling a new girlfriend, he is going to have sex with someone else?

But spend time and get to know him.

Don't be his next booty call, nor rush in before you know him. I suggest you keep a safe emotional distance and have more options than just him. Telling you he has a booty call and is looking for something serious is the standard player rap to get his foot in your door and get you hooked.

I really wouldn't waste my time on someone that has someone even if they do consider it just a booty call. You think his booty call considers herself one? You really don't know. You do know she exist however he wishes to put it. I am sure you will explore other option besides him, at least you should. His potential for being a lying cheater is huge. Maybe that's what he is really telling you he will have his booty calls while he looks for a serious relationship.

Not worth the drama in my book. A distraction for a better choice for fun and romance. Up to you.

I suppose I am not understanding what your definition of "red flag" is. If a man wanted a relationship with me, but told me he also had a "booty call," (having sex with another female whenever he wanted), then yes, I would call it a red flag. To me that means that he is not invested in having a real relationship with you and that you will be just another one of his "booty calls."

The dude is a player and you risk any number of STDs by having a sexual relationship with him.

If he wants a serious relationship, tell him to let the booty call go. You stay out of his bed and get to know him. See how far that goes.
I would not deal with him. Who would want a relationship with a person who is having sex with someone else while they are getting to know you?

Give him a "booty" right up the wazoo. What possible motivation could he have for telling you about his arrangement? Total honesty, is that his reason? He has been single for 3 months- how long has he known the booty girl? Was she the reason he became single?
He wants you to know about it and accept it so you won't object to it when he continues to do it after he "commits" to you. And get the blood test results for he and the booty girl. Would you have even protected sex with someone you knew had an std? If you wouldn't take a chance if you knew the other person was infected, why would you do it- if you don't know?

You met him three weeks ago. He has been honest that he got out of a committed relationship three months ago. Then he started a 'booty call' arrangement with another woman between the time he ended the relationship and met you. He says he is looking for a serious relationship.

Over the past three weeks since you met, how often have you seen each other or otherwise communicated (email, Facebook, text, etc.?) How did you meet?

Red flags for me are that he got out of a relationship and almost immediately started fooling around with another woman. This tells me there is a strong probability that he hasn't allowed himself to let go of the past and healed. Instead, he replaced one woman with another. It appears he may be trying to replace the 'booty call' with you. He may be serious, but I am concerned he is sliding from one available female to the next. People who do that generally do not fully let go of the past and tend to allow the emotional baggage to pile up. There is a higher chance of his repeating issues that caused the past break-up. There is also a higher chance of his shoving the baggage onto your shoulders. Deal with your own past, not his.

At three weeks after meeting, I might agree to be his friend and hang out, but I would not put myself in the position of having his past relationship baggage shoved onto my shoulders. It would take months of being friends and getting to know him before I would think about anything else with him.

I would also make certain that he hasn't produced a child with either woman or caught a disease.

Omg all you guys are very right, I told him the next morning that I wanted to just be frds, then a day later he texted me that he can not be a frd or in a relationship because he is in a relationship for 2yrs... I texted back OK...

I made it clear to him earlier that it would not happen with us having intercourse and he saved me the trouble. There was no emotional attachment and it wouldn't have bothered me if he had never called me ever again because I have already decided I do not want him in any way and I said frds to be nice.. Definitely a player, but i knew the game..

thanks guys

Omg all you guys are very right, I told him the next morning that I wanted to just be frds,

What is a "frds?"

I really wish people would use actual words and not the text speak.
