Sexual frustration is when your boyfriend is so awfully sick that he bans mouth kisses and limits visits (mostly so he can get back to his 18 hour sleep each day… it’s a fever thing with lots of flem involved… you would think that’s a turn off and it is but he’s still sexy) and you’re on your period and just started antibiotics so the effectiveness of your implanon *may* be altered, but the doctor says you can totally still have unprotected on your period and be safe, but you can’t have period sex anyway because of your sickly sexual partner, and then when your period finishes you have been advised to use condoms for the duration of the course of the antibiotics, and a further 5 days after. THAT’S 15 DAYS. I don’t actually remember what condoms feel like.
