Point blank, you're not ready for a realtionship...End it now, you've already messed up & then you don't even care nor want to come clean...You're young, if you think you're a sex addict or whatever excuse you wanna try to make, just be single & mess around with people that let you or whatever..don't do it at the expense of someone's feelings/heart/whatever...You can't even pull that whole we just got into a relationship thing like it's normal...once you decide to be in a relationship, it's monogamous unless stated otherwise, then you'd classify it as open if that's even really classifable b/c that's BS to me...but anyway, situations like this is how people end up with STDs (not knowing what or who their partner if they become partners is doing) & if you just kiss, it can cause the same problems b/c too many people engage in oral & go around kissing people & spreading herpes & stuff...People are so darn nasty...be responsible...a relationship is built on trust & you're already breaking that...Sex also isn't the sole purpose for a relationship or necessary & if it is then you need to get someone that fulfills that for you...you should just end it now so it won't be much harm done if any...
