This is really a question that admits of no universal answer on the Internet. In Europe, you would be welcomed and even encouraged to come forward for a blessing. In reading and talking with the American bishops, there are some dioceses where the bishop has forbidden the giving of individual blessings. There are other dioceses, such as New York City, where it is tolerated but not encouraged with any enthusiasm and is limited to a cleric imparting the blessing. There are other dioceses where the Extraordinary Ministers are specifically directed by the bishop to also give a blessing.
The diocesan bishop is the moderator of the liturgy for his diocese. I know the dubium on this issue was submitted many years ago to the Holy See. In fact, I also know a number of bishops were asking if we could have a resolution to this at the time of the Synod on the Eucharist in 2005…the request was even put into the lineamenta. Who knows? One day it may be answered.
It would be wholly inappropriate for me to offer any critique of these three very diverse approaches, since the decision is the bishop’s. If you are not motivated to seek an individual blessing, you should feel perfectly comfortable to stay in your place. If, on the other hand, you wish to receive a blessing when others go forward for Communion, I would encourage you to inquire beforehand what is the prescription (or proscription) that governs this matter for your diocese. It would only take a moment before Mass to ask the priest or deacon (Can one come forward for a blessing at Communion time?)…the answer will likely be a very simple “yes” or “no”.
