I'm going to take a 29yo's virginity and then break up with him
Why would you mess with him like this?
I'm looking for someone to break their virginity. I think he's the most ideal candidate for this situation
You shouldn't use someone for a one night stand unless they are okay with it. Ask him if he minds this first.
It's fine. He'll like it.
Using someone just to have sex with them is just a very immoral thing to do. I doubt that this person wants to have you break up with them immediately after taking their virginity. But yea, asking them first is the best option.
