Used to use a delay spray when younger and had hardly any control but not when Getty’s bj because of the taste. Also not when having a hj as we didn’t see the point. Just want to delay when having inter course. Stick to using it when you are just pleasuring him
So instead of using products, why not change things up within your technique? So try going slower, user less pressure and really tease and build up the anticipation. Then if he tells you he is getting close you can back off, can actually make a fun game out of it
Without using some sort of condom once spray has been administered I’d say it’s gonna be impossible to not get transference in mouth when giving oral unless you don’t use the spray until afterwards
So I gave him a quick hj during foreplay, let him do his thing on me then used some edging/slower/less pressure techniques for the bj and it worked great!
