Hey I'm 17 years old. Ummm I have started to make out with this girl... tonight would be the fourth time. The first time we did this was the like 2 weeks ago. And I thought that I worked fine. Then the following Tuesday I gave blood. And ever since then it does't seem to be working right. Like she will touch me and I won't come up. And when I do come up if we stop kissing for like 2 seconds... it will go back down. She thinks that I have ED... but I was just wondering if it was because I gave blood. I gave blood on Tuesday November 13 and Its Sunday November 18. Is it normal for this to happen?

It's only ED it if happens a lot, it's normal for it to happen sometimes.

Could be worry, esp after one failure, you worry and then it gets worst.

There are dozens of reasons, why a man can have failure.

It's true, it's not your fault so don't be embarrassed. It happens to pretty much every man once or twice in his life, ED is when it's very frequent to always.
