The best thing todo is introduce him as soon as possible to your family.
Things you can do to make the situation less awkward;
1) Just bring him over to your house one day as a friend or someone your studying with.
2) At least talk about him, your mum should know some history.
3) You really shouldn't be having sex as soon as you turn 16. Hence, nothing to worry about!
I'm really sorry, The Optimist- are you a boy or a girl? Do you mean 'come-out' as in tell your parents you're gay or 'come-out' as in tell your parents you're dating someone?
I don't expect it matters greatly in the advice I'm going to give you, but I suppose your parents acceptance of homosexuality may have an effect on how your parents react to your 'coming-out' ,if you're gay.
Be straight with them, but don't blast them with your boyf. Introduce him when no one else is there. If you break the news to them when there is an audience of their nearest & dearest- any objections they have against him may be challenged by others.
Let them have their say and don't get dragged in to an argument. Then tell them you've been dating very slowly for the past 10 months (tbh, this is a good achievement at your age- well done!)- and that you've both been respectful and sensible and have every intention of keeping it that way until you are both ready for the consequences.
And keep to your word. If you make promises to your parents (for ex; not seeing your boyf when you should be studying)- keep to them. Going behind their back, disobeying their rules, etc- it only shows them that you are not ready for a relationship. Then they will object to you having a boyfriend.
Remember- this one may the first of many. You have years of boyf vs parents drama to come. I guarentee it!
thank you once again
