Hey holl2007!
It´s sounds to me like you would be better off waiting for a steady realtionship, I think most of us are. Others don´t care.
I kind of wish I had waited, would have been nicer and more “special”, something I would rather have shared with a more special girl than how it turned out. Didn´t know that at the time though and she felt special right then.
Waiting until marriage isn´t someting I would do, wouldn´t want to wait that long to let the pig out of the bag, so to speak. Could turn out you´re not really sexually compatible, and then you´re stuck there. But then if you do everything except actual penetration you´ll probably know anyway. But that could possible preassure you to enter marriage sooner than you should.
I have great respect for anyone who feels it´s worth waiting for, but don´t beat yourself up if it doesn´t turn out like you want, no need to feel guilt or anything like that. Stay true to yourself as much as you can, everyone make misstakes, world keeps spinning anyway.
Condoms I don´t know about, get some free samples at some clinic and try them out yourself. Could probably do that at the student health office, if you have one.
