Hi, I had protected sex with my partner, but I reused a condom, which I applied but was not not involved in sexual intercourse day before yesterday. So pulled it off and kept in the condom box, Yesterday , when we were making out I mistakenly chose the same one to apply on the penis. I am worried about now, by reading stuff i got to know about STI, I am really worried for my partner now, as i feeling the guilt n risk of getting her infected. What ro do now, when to go for checkup, which specialist (urologist, gynac, general physician or sexologists) Should i weight for 3-4 days till the body show some symptoms or go immediately for checkup? Please i requests the doctors to help me asap!!
