Well in the UK that's perfectly legal. but you need to think about whether you are mature enough to be going with this 23 year old and if it would be a good relationship for the baby(if you're pregnant) i disagree quite strongly with babies being brough up in environments where the parents aren't in a stable relationship and could be arguing and fighting alot.

If this man can be trusted to stay faithful to you and you think you are mature enough to continue the relationship then i don't see a problem with it.(Athough i'm slightly biased since i'm 17 and y boyfriend is 26). My advice is that if you are both in love and want the relationship to work, it will. You might get alot of discouragement and fun made about you from other people, because in my experience it has been quite bad for my boyfriend and I,but as i have already said if you are ready to be in a stable relationship then it shouldn't matter too much what other people think.

Uhm that's my 2 cents, you should probably get some professional advice because should you be pregnant, there are ALOT of things to think about financially and timewise when having a child.
