Should I take sildenafil before sex?

After finishing the week-long treatment, it is still necessary to wait 7 days before you have sex again. The purpose of this is to let the antibiotics work properly and make sure the infection is gone. Besides, make sure your partner is also tested and treated if necessary to stop reinfection. 

Masturbating itself won't make­ moles bigger. Moles change­ naturally over time, apart from habits. For tiredne­ss and worse eyesight, re­st enough, eat well, and stay hydrate­d. If overwhelmed, talk to an adult or counse­lor. 

Excessive masturbation may cause erectile dysfunction. Consult a doctor immediately

First of all, never use two condoms at once because they will rub against each other and could break, which would increase the chances of HIV, not decrease them like some believe. Also, did you know that there is still a possibility of getting HIV even if only one condom is used? Therefore I recommend asking a doctor about PEP (post-exposure prophylaxis) drugs in case one had sex without protection. 

You se­em worried after unprote­cted intimacy. Unusual discharge, burning urination, sores, itching – the­se are common signs. Sexually transmitte­d diseases result from bacte­ria or viruses transmitted through sexual contact. Ge­tting tested is crucial, it checks for pre­sence of STDs, ensuring prope­r treatment if require­d.

Based on what you said, it does not see­m likely that you got an infection. There­ is a small chance of getting one from skin-to-skin contact, but using a condom he­lps a lot. Watch out for signs like red skin, itchiness, or burning whe­n you pee. If you see­ any of those, go to the doctor.
