Should I have sex?!?

I'm a 16 year old female and I have been thinking about having sex with one of my really good guy friends. We are really close, but we aren't officially dating. we are supportive of each other and we both feel really comfortable with each other. I like him a lot, and I keep having dreams about where him and I have sex. I love him as a friend, he's such a great guy!!! but... I really like him, in a romantic, sexual way. And I can't decide if sex is right for now. I want to have sex because he makes me feel so good like no other guy, & he gives me such amazing, special, happy feelings. he's very attractive. I'm questioning it b/c I don't want to ruin our friendship , or make things weird. Also, I don't wanna risk getting an STD/getting pregnant. I know he can use a condom but I'm so scared it will slip off, break, etc. and I'll get pregnant . I can't get pregnant, my life will be ruined forever. I want to experiment with him and do things with him so bad, I'm so emotionally attached to him that it's like if I don't have sex, I'll feel like I'm missing out and not getting the most out of him.he's mentioned a few times that he was interested in having sex too but not as strongly as me. Btw I'm a virgin and he's never hooked up with a girl before. Also does it hurt your first time? please answer respectfully and truthfully. Is it really worth it? Do you think I should? Pros? Cons? Feel free to share any experiences (if you have any) and give me some advice about this. Thank you!
