I had very rough sex with my girlfriend of 2 years the other day and it was dry and sore during. The following day I noticed one small scab on the glans of my penis, and two abrasions on the shaft. The two on the shaft have been moderately sore for the following two days but they have no discharge or other bumps near them, they are all individual (what appear to be abrasions) I am guessing from the friction.
Should I be concerned about STDs? My gut feeling was that if the sex was not painful at first but it was at the end, that is what caused them...
