I don't think giving him a timeline is a good idea. What if x month comes along and you are not ready? It will it may add more frustration than anything. I would try to be open and honest with him about it. That is part of a healthy releationship, to be able to be honest and have your feelings/needs respected. If he is resptful of your needs he will understand. I'm not saying he won't ask for sex or tell you that is something he is ready for, but he shouldn't make you feel pressured. Sex should come naturally and you will now when you have that level of trust with someone.

Also, having sex too soon can make things complicated. If you are not ready and he coherences you into it, you are sacrificing your own needs for hid. That isn't something you want as part of a healthy releationship. Having sex too soon can also make him lack respect for you. If he feels like he can pressure you into things, then he can walk all over your feelings and needs.

If I had to put a time on it, I would say ,2 weeks is too soon and a after a year the feeling may not be there. The first time I had sex I just knew. I felt a large sense of trust in my partner and I was willing to expierence the closeness sex brings. There is nothing else like it and you feel much more connected to the person when you are ready. I hope things work out and don't forget you own needs.
