Hey. I think that as long as BOTH OF YOU ARE responsible and accept the responsibilities that come with sex, then go for it. Be safe and prevent any chance of an unwanted pregnancy.
Keep the communication open and do things when you are comfortable with them. If you are not or don't want to you don't have to. Relationships are about compromising so as longs as both of you understand it and are willing to work into having a healthy relationship then there's nothing wrong with experimenting.
Read and learn as much as you can before doing certain things so that you know what type of things to take into consideration and what exactly are you don't. BE PREPARE, DON'T EXPECT SURPRISES!
Talk with your boyfriend and communicate. Good Luck. Keep it safe!
