So my girlfriend and I are starting to have sex for the first time for both of us. The first time we had sex I wore a normal trojan condom. I didn't even come close to ejaculating (I figured it was because I was feeling a little sick) but maybe could it be because the condom was too tight? We had sex a second time and I used a magnum and it felt like it was on better but I'm not sure. I don't know what it is supposed to feel like so how do I know? Should I use the average size and have it be a little tight or should I use the magnum? The second time I did come and it felt a lot better. I'm just worried that the magnum might be too big even though it felt comfortable. My penis is 7 inches long with a girth of about 3.4

Thanks!

I'm sorry I mistyped. My girth is about 5.4 (I think that is around 5 3/8" in other terms)
