I didn't post it to brag, or to be cute, but because it's what really happened.

My first time is described here: Wedding Night Virgins , and you may want to look at other posts in that thread - they point you (and your B/F!) to some good advice.
YES! It runs thru our movies, advertising, novels - wherever you look, the sex is almost always collosal and stupendous. Even the first time. And if it isn't, that becomes an instant justification for somebody to move on to another partner. Help your B/F understand something that you seem to be catching on to: Like golf, long division, public speaking, or a jillion other activities the first attempts are seldom even mediocre, but it gets better with practice.
