Desperation

So I’ve recently been fooling around with this guy a few years older than I am. I don’t find him physically or mentally attractive but I do want to keep exploring sexual things. If not with him, I have no one else to experiment with and I don’t have the confidence to meet someone else. I know I’ve been doing this out of desperation which I know is a bit sad. Is this bad of me to do? I know he doesn’t expect more than fwb from me so it’s not leading him on that I’m worried about. Do any of you guys ever do things like this even if they aren’t who particularly like? Or many even make you feel a little cheap?
