not sure what the question is but i will say..that is in some cases how addiction starts. you make up an excuse to use and it just goes from there. Also if you need to take drugs or get drunk before you have sex..you shouldn't be having sex!!!!
hey, if your friends have to take pills or get drunk to have sex with someone - hah
then maybe, just maybe they really do not want to and shouldn't be ??!!?!
I'm sorry....I am not clear on the question either....if you could clarify it and give us a little more info we would be happy to try and help you.
Are you concerned they are addicted and are using the sex as an excuse? Not sure what your question or concern is. Can you give a little more information?
