I am a 16 year old gay male and last night me and my boyfriend tried to have anal sex for the first time. I had ejaculated about 45 minutes before hand and I had an erection when I put on the condom but when I went to try and have sex with him, I lost my erection and I couldn't get it back. This was very embarrassing for me. Also when my boyfriend tries to give me oral sex, I cannot climax at all. Is there something wrong with me because I lost my erection?
I am worried in case it means that I am not gay or that I don't fancy him anymore. I was tired at the time and so was my boyfriend but he was able to have sex with me and keep his erection.
Also, my boyfriend is able to masturbate and ejaculate several times in the space of an hour but after I ejaculate once it takes me a few hours to be able to do so again, does this mean I have a problem?
PLEASE HELP!

Every man has different "recovery times" so to speak after ejaculation, that's not your problem it is normal for some men to take longer.

The problem with not being able to gain an erection may not be because you don't care for your partner or anything like that, it may just be a small bit of erectile dysfunction, which is nothing to be embarrassed about, it is really quite common. If it keeps happening and really bothers you, you can look into medications for erectile dysfunction.

As for not being able to climax, I don't know a lot about that.. perhaps you just need a change or to try something new and exciting? Talk to your partner about things you enjoy and perhaps you can fix that problem together.

Good luck and remember to always use protection!

Recovery times can vary among men, and even with the same man depending on mental state, physical state, etc.

Being tired or a little stressed (1st time sex) can absolutely hurt your erection.
