hi as long as you have a healthy mouth ten things should be ok as for her juices just don't worry they wont harm you just enjoy them and the taste. just hope she returns the favour. good luck
i blowjob her and insert my toung in any chance she get infected from bacteria of mouth/breath? . we both are healthy and without any std. should i only lick on her lips(over vagina and clitoris) rather inserting tounge to avoid spreading any kind of infection to her? . also is there any harm if swallow the juice from her? or if she swallow from me?
