My girlfriend and I have been going out for about 3 months and she wants to get more intimate. What should I do?
Communication is the key - think about how you feel about this and then talk to her about what you want, how you feel and encourage her to do same. If getting more intimate feels okay for you, that's fine, but if you don't feel ready yet, that's OK too - just do what feels right for you, if she cares about you she will respect your feelings and decision.
If you decide that you are both ready to become more intimate, also talk about safe sex - how you will protect yourself and each other. The important thing is that you don't rush into anything and that you are both comfortable and happy with whatever you do.
