thanks for explaining the backstory. Glad it's a case of me jumping to conclusions. I thought you watched him for 2 years and started talking not that long ago? Granted, you did watch him thoroughly since you had a real crush.
That's definitely hard and its great he tried to be responsible and I'll pray for him. Not knowing the particulars of his relationship with his ex, the one thing I would caution is if he asks for s** (he may ask or already consider you friends with benefits meaning a friend he can be physically intimate with without the burden of relationship), no matter how much you may be into him or be curious to experience it, try to wait until marriage (or at least if you can't, with someone you could see yourself having a kid with and they too want to be a parent someday, because it can still happen even with proper precautions).
In addition to what's in the bible, it's possible to become addicted to the pleasure of the flesh (hence the warning about self-control in another thread, the one some guys were comparing pe*** sizes) which can result in developing STD's. If and when you do get married, if your husband isn't as satisfying as previous partners (especially true if his pe*** isn't as large when erect as to what you experienced), that dissatisfaction could ultimately lead to adultery and/or divorce. And finally, it's harder to be faithful because you may feel insecure in your relationship (it's a way for Satan to disrupt your peace and stability of your marriage and relationship with G**). Song of Solomon actually talks about s** (it's written from one of Solomon's wives pov), which is a promise from G** if you choose to be patient and wait until marriage for s**.
I've met people who did both s** before and s** after marriage and those who waited until marriage have shared they felt really satisfied in waiting in comparison to those who didn't wait
