Re: Control Issues!
Don't worry about it!
I think most young ladies are aware that guys will often pop pretty fast. Condoms may help a little and, yes, you need to be wearing one. Don't want to get anyone pregant or catch any diseases.
Just tell her, before you start, that she has you sooooo turned on and you don't know how long you can last. Before that, try to get her off manually or orally so, at least, she will have had hers (and remember, many women find it difficult to orgasm via intercourse). If it happens fast, tell her how good she was. You can always go a second round.
