you should decide what your expectations are and set up some ground rules.
condoms (period. no exceptions) they may bring but may try to talk you into doing some things first without them. (They may say...oh I will wear them when I get ready to cum but not first. First I wanna feel you bareback)... That should be a strong NO.
If there is anything off limits you should say (like tying up - personally I wouldn't do that with someone I met online and didn't know well enough to trust with my life) another example is certain kinks that my be off limits - you should both know what you want to do sexually before you meet.
Do you know these guys well enough to be comfortable with this? Have you had a chance to cam with them? Or exchange pictures? Get enough information to feel they are real? (by the way, I suggest that you not give them your full real name... that could be used against you.) Do you feel a "connect" with either of these guys?
Are you comfortable doing this at your home? Will someone else know (a friend perhaps that can come to your rescue if things go askew?) There are lots of good pple out there, but there are some creepy, scary ppl too that have less than honest intentions.
If you've never done anything sexually (at all) why now? why them? what is the catalyst behind having sex with strangers for the first time? have you had time to get to know them very well? would you not consider doing this with someone special in your life? someone that knows you and your orientation?
The first time is going to be something you remember for the rest of your life. Not trying to talk you out of it but
just be sure this is what you want and how you want to remember your first time. Be picky about the guy you meet. Be very picky.
good luck
If you decide to go through with this the main thing you should do is BE SAFE!! There is only one you.... you cannot be replaced
