I can't stop thinking about giving strangers bj's
What makes you obsess about giving strangers bj's?
I like sex with strangers because it's more exciting.
Having sex of any kind with strangers is dangerous behavior because you don't know if those people might have STDs. Also, have you thought about seeking professional help? It sounds like you might be addicted to sex which might be an unhealthy lifestyle.
Yes, I'm addicted to the excitement of having sex with strangers but I see no problem with it.
Though it may be exciting, you are really putting yourself at risk for STD's. You should make sure to take all precautions and use protection if you are going to continue doing this.
