my entire life i have looked 5+ years older than i really am and having gone to para military school so I act it too. for somethings its great but for dating it can be difficult. we met at a cafe, she is 23 and I am 20. Because of living in the US i technically cant drunk yet, so we have been doing picnics where i supply the wine. she is unaware of how old i am, its just never come up....

Do you think she will have an issue? How do i go about it ?
