Never ever do it. Never in your life. There are two types of women in these situations.
Type A (rare): the most don't give a damn about your life, nor what you're going through, you're just an option in case she wants some sex. Situations like this normally work out, because you don't really care about getting rid of her like that, nor would it be that difficult to get her back.
Type B (most common):
The one that really does like you, cares about you, and wants to be with you in the end, but is willing to move at your pace. This sounds great, but a lot of these women are low-key thots. A lot of dudes can get in their ear and get them to do anything. Furthermore, a lot of them don't like you, they just like the challenge. As soon as they get with you, the feelings are going to slowly start to fade away
We were always better friends than wha our idea of wha a couple was. sohh we kept that contact. Other episodes occurred on both sides but wha stayed was
But as we compared notes wha worked & wha diddnt with others we realized as much as we are in many ways personality wise different but goals wise we on the same page 2 kids 3 properties & over a dozen years later here we are. It aint story book but in its own wierd way it works, weve outlasted most of our friends & neighbors and still clicking along 
..we were close friends for like 6 years (platonic)..but thats an anomaly...none of the other FWBs ive had like that were that long..the longest after that was 3 years and THAT one there was no chance i was going into a relationship with that one
