Absolutely none of these are necessarily a consequence of sex, given a healthy and productive attitude toward physicality and interpersonal relationships.
I am genuinely sympathetic that you seem to associate these feelings with sexual relationships.
I appreciate the sympathy however (I hope) I can enjoy sex as much as anyone else.
My point is rather that describing sex as only joyful (also in a context of modern teenagers) is quite shallow.
You can look no further but to a few pop songs, watch a random movie or read some good poetry to learn that sex as a driving force is leading to confusion, suffering etc. It is also a force beyond our control on some level and as such could lead to serious life consequences - you can make some dumb life decision driven by sex.
Also historically and in many different cultures sex is seen rather as confusing force. People had been choosing lifetime celibacy, chastity etc. for a reason.
