I've done BBFS with a WL once. But once you start, they will always do BBFS from then on. Which has both positives and negatives.

The positive is that it feels fkin great. Condoms really suck, especially getting them put on.

The negatives are: STD risk, pregnancy risk, visa risk, if the girl is good and you regretted BBFS, kind of difficult to go back and just do normal FS.

Honestly I do not recommend, but would honestly feel the temptation each time...
