Brother. Your not alone. Everyone feels like you, well, with the exception of wifes and husbands and people who've been doing it with the same partner for years.
But for people like us, not experience and doing it a first time with a new partner. It's just scary.
Its like, how do you start? How you get into position, how to make it romantic and not just porno. The condom use, pressure of putting it on before she falls asleep. Hard? Slow? Soft? Look deep into eyes? Look at your own performance?
How long? Man, It sucks. Then we have the whole body thing, I have no 6-pack, I'm ugly. My weapon is too small and so on.
It sucks. Your not alone.
THinking about it. Sex sucks.
I'm more of a huger and grinder person guess.
