How to SB with an unattractive guy?

To start I’m 35F brand new to SBing. I look younger than my age which is why I think this is working for now. I found a guy who wants PPM (I know, I’ve read the forums about the dangers of PPM). But I think in this case, it will work best for the time being. I’ve been chatting with this guy and he seems very nice BUT he is very unattractive. That’s the part that turns me off. Obviously I need the money or I wouldn’t be doing this. So how do you guys get over SBing with an unattractive man?
